This gives the application the greatest flexibility in +handling asynchronous events. +.Pp +It's also recommended that interfaces take only a single block as the last +parameter. This is both for consistency across projects, as well as the visual +aesthetics of multiline blocks that are declared inline.

For example: +.Pp +.Bd -literal -offset indent +read_async(file, callback_queue, ^{ + printf("received callback.\\n"); +}); +.Ed +.Pp +When function pointer alternatives to interfaces that take blocks are provided, +the argument order of the function signature should be identical to the block +variant; with the exception that the block argument is replaced with a context +pointer, and a new last parameter is added, which is the function to call. +.Pp +The function based callback should pass the context pointer as the first +argument, and the subsequent arguments should be identical to the block based +variant (albeit offset by one in order). +.Pp +It is also important to use consistent naming.

These same functions can also be used +for efficient notification of the completion of asynchronous blocks (a.k.a. +callbacks). +.Sh TEMPORAL SYNCHRONIZATION +Synchronization is often required when multiple threads of execution access +shared data concurrently. The simplest form of synchronization is +mutual-exclusion (a lock), whereby different subsystems execute concurrently +until a shared critical section is entered. In the +.Xr pthread 3 +family of procedures, temporal synchronization is accomplished like so: +.Bd -literal -offset indent +int r = pthread_mutex_lock(&my_lock); +assert(r == 0); + +// critical section + +r = pthread_mutex_unlock(&my_lock); +assert(r == 0); +.Ed +.Pp +The +.Fn dispatch_sync +function may be used with a serial queue to accomplish the same style of +synchronization. For example: +.Bd -literal -offset indent +dispatch_sync(my_queue, ^{ + // critical section +}); +.Ed +.Pp +In addition to providing a more concise expression of synchronization, this +approach is less error prone as the critical section cannot be accidentally +left without restoring the queue to a reentrant state. +.Pp +The +.Fn dispatch_async +function may be used to implement deferred critical sections when the result +of the block is not needed locally. Deferred critical sections have the same +synchronization properties as the above code, but are non-blocking and +therefore more efficient to perform. For example: +.Bd -literal +dispatch_async(my_queue, ^{ + // critical section +}); +.Ed +.Sh BACKGROUND CONCURRENCY +.The +.Fn dispatch_async +function may be used to execute trivial backgound tasks on a global concurrent +queue. For example: +.Bd -literal +dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT,0), ^{ + // background operation +}); +.Ed +.Pp +This approach is an efficient replacement for +.Xr pthread_create 3 . +.Sh COMPLETION CALLBACKS +Completion callbacks can be accomplished via nested calls to the +.Fn dispatch_async +function. It is important to remember to retain the destination queue before the +first call to +.Fn dispatch_async , +and to release that queue at the end of the completion callback to ensure the +destination queue is not deallocated while the completion callback is pending. +For example: +.Bd -literal +void +async_read(object_t obj, + void *where, size_t bytes, + dispatch_queue_t destination_queue, + void (^reply_block)(ssize_t r, int err)) +{ + // There are better ways of doing async I/O. + // This is just an example of nested blocks. + + dispatch_retain(destination_queue); + + dispatch_async(obj->queue, ^{ + ssize_t r = read(obj->fd, where, bytes); + int err = errno; + + dispatch_async(destination_queue, ^{ + reply_block(r, err); + }); + dispatch_release(destination_queue); + }); +} +.Ed +.Sh RECURSIVE LOCKS +While +.Fn dispatch_sync +can replace a lock, it cannot replace a recursive lock. Unlike locks, queues +support both asynchronous and synchronous operations, and those operations are +ordered by definition. A recursive call to +.Fn dispatch_sync +causes a simple deadlock as the currently executing block waits for the next +block to complete, but the next block will not start until the currently +running block completes. +.Pp +As the dispatch framework was designed, we studied recursive locks. We found +that the vast majority of recursive locks are deployed retroactively when +ill-defined lock hierarchies are discovered. As a consequence, the adoption of +recursive locks often mutates obvious bugs into obscure ones. This study also +revealed an insight: if reentrancy is unavoidable, then reader/writer locks are +preferable to recursive locks. Disciplined use of reader/writer locks enable +reentrancy only when reentrancy is safe (the "read" side of the lock). +.Pp +Nevertheless, if it is absolutely necessary, what follows is an imperfect way of +implementing recursive locks using the dispatch framework: +.Bd -literal +void +sloppy_lock(object_t object, void (^block)(void)) +{ + if (object->owner == pthread_self()) { + return block(); + } + dispatch_sync(object->queue, ^{ + object->owner = pthread_self(); + block(); + object->owner = NULL; + }); +} +.Ed +.Pp +The above example does not solve the case where queue A runs on thread X which +calls +.Fn dispatch_sync +against queue B which runs on thread Y which recursively calls +.Fn dispatch_sync +against queue A, which deadlocks both examples. This is bug-for-bug compatible +with nontrivial pthread usage. In fact, nontrivial reentrancy is impossible to +support in recursive locks once the ultimate level of reentrancy is deployed +(IPC or RPC). +.Sh IMPLIED REFERENCES +Synchronous functions within the dispatch framework hold an implied reference +on the target queue. In other words, the synchronous function borrows the +reference of the calling function (this is valid because the calling function +is blocked waiting for the result of the synchronous function, and therefore +cannot modify the reference count of the target queue until after the +synchronous function has returned). +For example: +.Bd -literal +queue = dispatch_queue_create("com.example.queue", NULL); +assert(queue); +dispatch_sync(queue, ^{ + do_something(); + //dispatch_release(queue); // NOT SAFE -- dispatch_sync() is still using 'queue' +}); +dispatch_release(queue); // SAFELY balanced outside of the block provided to dispatch_sync() +.Ed +.Pp +This is in contrast to asynchronous functions which must retain both the block +and target queue for the duration of the asynchronous operation (as the calling +function may immediately release its interest in these objects). +.Sh FUNDAMENTALS +Conceptually, +.Fn dispatch_sync +is a convenient wrapper around +.Fn dispatch_async +with the addition of a semaphore to wait for completion of the block, and a +wrapper around the block to signal its completion. See +.Xr dispatch_semaphore_create 3 +for more information about dispatch semaphores.

This FIFO completion behavior is sometimes simply described as a "serial queue." +Queues are not bound to any specific thread of execution and blocks submitted +to independent queues may execute concurrently. +Queues, like all dispatch objects, are reference counted and newly created +queues have a reference count of one. +.Pp +The optional +.Fa label +argument is used to describe the purpose of the queue and is useful during +debugging and performance analysis. By convention, clients should pass a +reverse DNS style label. +If a label is provided, it is copied. If a label is not provided, then +.Fn dispatch_queue_get_label +returns an empty C string. +For example: +.Pp +.Bd -literal +my_queue = dispatch_queue_create("com.example.subsystem.taskXYZ", NULL); +.Ed +.Pp +The +.Fa attr +argument is reserved for future use and must be NULL. +.Pp +Queues may be temporarily suspended and resumed with the functions +.Fn dispatch_suspend +and +.Fn dispatch_resume +respectively. Suspension is checked prior to block execution and is +.Em not +preemptive. +.Sh MAIN QUEUE +The dispatch framework provides a default serial queue for the application to use. +This queue is accessed via +.Fn dispatch_get_main_queue . +Programs must call +.Fn dispatch_main +at the end of +.Fn main +in order to process blocks submitted to the main queue. (See the compatibility +section for exceptions.) +.Sh GLOBAL CONCURRENT QUEUES +Unlike the main queue or queues allocated with +.Fn dispatch_queue_create , +the global concurrent queues schedule blocks as soon as threads become +available (non-FIFO completion order). The global concurrent queues represent +three priority bands: +.Bl -bullet -compact -offset indent +.It +DISPATCH_QUEUE_PRIORITY_HIGH +.It +DISPATCH_QUEUE_PRIORITY_DEFAULT +.It +DISPATCH_QUEUE_PRIORITY_LOW +.El +.Pp +Blocks submitted to the high priority global queue will be invoked before those +submitted to the default or low priority global queues. Blocks submitted to the +low priority global queue will only be invoked if no blocks are pending on the +default or high priority queues. +.Pp +.Sh RETURN VALUES +The +.Fn dispatch_queue_create +function returns NULL on failure. +.Pp +The +.Fn dispatch_queue_get_label +function always returns a valid C string. An empty C string is returned if the +.Fa label +was NULL creation time. +.Pp +The +.Fn dispatch_get_main_queue +function returns the default main queue. +.Pp +The +.Fn dispatch_get_current_queue +function always returns a valid queue. When called from within a block submitted +to a dispatch queue, that queue will be returned. If this function is called from +the main thread before +.Fn dispatch_main +is called, then the result of +.Fn dispatch_get_main_queue +is returned. Otherwise, the result of +.Fo dispatch_get_global_queue +.Fa DISPATCH_QUEUE_PRIORITY_DEFAULT +.Fa 0 +.Fc +will be returned in all other cases. +.Pp +The +.Fn dispatch_main +function never returns. +.Sh TARGET QUEUE +The +.Fn dispatch_set_target_queue +function updates the target queue of the given dispatch object. The target +queue of an object is responsible for processing the object. Currently only +dispatch queues and dispatch sources are supported by this function. The result +of using +.Fn dispatch_set_target_queue +with any other dispatch object type is undefined. +.Pp +The new target queue is retained by the given object before the previous target +queue is released. The new target queue will take effect between block +executions, but not in the middle of any existing block executions +(non-preemptive). +.Pp +The priority of a dispatch queue is inherited by its target queue. +In order to change the priority of a queue created with +.Fn dispatch_queue_create , +use the +.Fn dispatch_get_global_queue +function to obtain a target queue of the desired priority. The +.Fa flags +argument is reserved for future use and must be zero. Passing any value other +than zero may result in a +.Vt NULL +return value. +.Pp +The target queue of a dispatch source specifies where its event handler and +cancellation handler blocks will be submitted. See +.Xr dispatch_source_create 3 +for more information about dispatch sources. +.Pp +The result of passing the main queue or a global concurrent queue to the first +argument of +.Fn dispatch_set_target_queue +is undefined. +.Pp +Directly or indirectly setting the target queue of a dispatch queue to itself is undefined. +.Sh CAVEATS +Code cannot make any assumptions about the queue returned by +.Fn dispatch_get_current_queue . +The returned queue may have arbitrary policies that may surprise code that tries +to schedule work with the queue. The list of policies includes, but is not +limited to, queue width (i.e. serial vs. concurrent), scheduling priority, +security credential or filesystem configuration. Therefore, +.Fn dispatch_get_current_queue +.Em MUST +only be used for identity tests or debugging. +.Sh COMPATIBILITY +Cocoa applications need not call +.Fn dispatch_main . +Blocks submitted to the main queue will be executed as part of the "common modes" +of the application's main NSRunLoop or CFRunLoop. +However, blocks submitted to the main queue in applications using +.Fn dispatch_main +are not guaranteed to execute on the main thread. +.Pp +The dispatch framework is a pure C level API. As a result, it does not catch +exceptions generated by higher level languages such as Objective-C or C++. +Applications +.Em MUST +catch all exceptions before returning from a block submitted to a dispatch +queue; otherwise the internal data structures of the dispatch framework will be +left in an inconsistent state. +.Pp +The dispatch framework manages the relationship between dispatch queues and +threads of execution. As a result, applications +.Em MUST NOT +delete or mutate objects that they did not create. The following interfaces +.Em MUST NOT +be called by blocks submitted to a dispatch queue: +.Bl -bullet -offset indent +.It +.Fn pthread_cancel +.It +.Fn pthread_detach +.It +.Fn pthread_join +.It +.Fn pthread_kill +.It +.Fn pthread_exit +.El +.Pp +Applications +.Em MAY +call the following interfaces from a block submitted to a dispatch queue if +and only if they restore the thread to its original state before returning: +.Bl -bullet -offset indent +.It +.Fn pthread_setcancelstate +.It +.Fn pthread_setcanceltype +.It +.Fn pthread_setschedparam +.It +.Fn pthread_sigmask +.It +.Fn pthread_setugid_np +.It +.Fn pthread_chdir +.It +.Fn pthread_fchdir +.El +.Pp +Applications +.Em MUST NOT +rely on the following interfaces returning predictable results between +invocations of blocks submitted to a dispatch queue: +.Bl -bullet -offset indent +.It +.Fn pthread_self +.It +.Fn pthread_getschedparam +.It +.Fn pthread_get_stacksize_np +.It +.Fn pthread_get_stackaddr_np +.It +.Fn pthread_mach_thread_np +.It +.Fn pthread_from_mach_thread_np +.El +.Pp +While the result of +.Fn pthread_self +may change between invocations of blocks, the value will not change during the +execution of any single block. Because the underlying thread may change beteween +block invocations on a single queue, using per-thread data as an out-of-band +return value is error prone. In other words, the result of calling +.Fn pthread_setspecific +and +.Fn pthread_getspecific +is well defined within a signle block, but not across multiple blocks. Also, +one cannot make any assumptions about when the destructor passed to +.Fn pthread_key_create +is called. The destructor may be called between the invocation of blocks on +the same queue, or during the idle state of a process. +.Pp +The following example code correctly handles per-thread return values: +.Bd -literal -offset indent +__block int r; +__block int e; +dispatch_sync(queue, ^{ + r = kill(1, 0); + // Copy the per-thread return value to the callee thread + e = errno; +}); +printf("kill(1,0) returned %d and errno %d\n", r, e); +.Ed +.Pp +Note that in the above example +.Va errno +is a per-thread variable and must be copied out explicitly as the block may be +invoked on different thread of execution than the caller. Another example of +per-thread data that would need to be copied is the use of +.Fn getpwnam +instead of +.Fn getpwnam_r . +.Pp +As an optimization, +.Fn dispatch_sync +invokes the block on the current thread when possible. In this case, the thread +specific data such as +.Va errno +may persist from the block until back to the caller.

The cancellation handler may be specified via +.Fn dispatch_source_set_cancel_handler . +This cancellation handler is invoked only once, and only as a direct consequence +of calling +.Fn dispatch_source_cancel . +.Pp +.Em Important: +a cancellation handler is required for file descriptor and mach port based +sources in order to safely close the descriptor or destroy the port. Closing the +descriptor or port before the cancellation handler has run may result in a race +condition: if a new descriptor is allocated with the same value as the recently +closed descriptor while the source's event handler is still running, the event +handler may read/write data to the wrong descriptor. +.Pp +.Sh DISPATCH SOURCE TYPES +The following section contains a summary of supported dispatch event types and +the interpretation of their parameters and returned data. +.Pp +.Vt DISPATCH_SOURCE_TYPE_DATA_ADD , +.Vt DISPATCH_SOURCE_TYPE_DATA_OR +.Pp +Sources of this type allow applications to manually trigger the source's event +handler via a call to +.Fn dispatch_source_merge_data . +The data will be merged with the source's pending data via an atomic add or +logic OR (based on the source's type), and the event handler block will be +submitted to the source's target queue.

See +.Xr fcntl 2 +for additional information about setting the +.Vt O_NONBLOCK +flag on a file descriptor. +.Pp +.Vt DISPATCH_SOURCE_TYPE_SIGNAL +.Pp +Sources of this type monitor signals delivered to the current process. The +.Fa handle +is the signal number to monitor (int) and the +.Fa mask +is unused and should be zero. +.Pp +The data returned by +.Fn dispatch_source_get_data +is the number of signals received since the last invocation of the event handler +block. +.Pp +Unlike signal handlers specified via +.Fn sigaction , +the execution of the event handler block does not interrupt the current thread +of execution; therefore the handler block is not limited to the use of signal +safe interfaces defined in +.Xr sigaction 2 . +Furthermore, multiple observers of a given signal are supported; thus allowing +applications and libraries to cooperate safely. However, a dispatch source +.Em does not +install a signal handler or otherwise alter the behavior of signal delivery. +Therefore, applications must ignore or at least catch any signal that terminates +a process by default. For example, near the top of +.Fn main : +.Bd -literal -offset ident +signal(SIGTERM, SIG_IGN); +.Ed +.Pp +.Vt DISPATCH_SOURCE_TYPE_TIMER +.Pp +Sources of this type periodically submit the event handler block to the target +queue on an interval specified by +.Fn dispatch_source_set_timer . +The +.Fa handle +and +.Fa mask +arguments are unused and should be zero. +.Pp +A best effort attempt is made to submit the event handler block to the target +queue at the specified time; however, actual invocation may occur at a later +time. +.Pp +The data returned by +.Fn dispatch_source_get_data +is the number of times the timer has fired since the last invocation of the +event handler block. +.Pp +The function +.Fn dispatch_source_set_timer +takes as an argument the +.Fa start +time of the timer (initial fire time) represented as a +.Vt dispatch_time_t . +The timer dispatch source will use the same clock as the function used to +create this value. (See +.Xr dispatch_time 3 +for more information.) The +.Fa interval , +in nanoseconds, specifies the period at which the timer should repeat. All +timers will repeat indefinitely until +.Fn dispatch_source_cancel +is called. The +.Fa leeway , +in nanoseconds, is a hint to the system that it may defer the timer in order to +align with other system activity for improved system performance or reduced +power consumption. (For example, an application might perform a periodic task +every 5 minutes with a leeway of up to 30 seconds.) Note that some latency is +to be expected for all timers even when a value of zero is used. +.Pp +.Em Note : +Under the C language, untyped numbers default to the +.Vt int +type. This can lead to truncation bugs when arithmetic operations with other +numbers are expected to generate a +.Vt uint64_t +sized result. When in doubt, use +.Vt ull +as a suffix. For example: +.Bd -literal -offset indent +3ull * NSEC_PER_SEC +.Ed +.Pp +.Vt DISPATCH_SOURCE_TYPE_VNODE +.Pp +Sources of this type monitor the virtual filesystem nodes for state changes. +The +.Fa handle +is a file descriptor (int) referencing the node to monitor, and +the +.Fa mask +may be one or more of the following: +.Bl -tag -width "XXDISPATCH_VNODE_ATTRIB" -compact -offset indent +.It \(bu DISPATCH_VNODE_DELETE +The referenced node was removed from the filesystem namespace via +.Xr unlink 2 . +.It \(bu DISPATCH_VNODE_WRITE +A write to the referenced file occurred +.It \(bu DISPATCH_VNODE_EXTEND +The referenced file was extended +.It \(bu DISPATCH_VNODE_ATTRIB +The metadata attributes of the referenced node have changed +.It \(bu DISPATCH_VNODE_LINK +The link count on the referenced node has changed +.It \(bu DISPATCH_VNODE_RENAME +The referenced node was renamed +.It \(bu DISPATCH_VNODE_REVOKE +Access to the referenced node was revoked via +.Xr revoke 2 +or the underlying fileystem was unmounted. +.El +.Pp +The data returned by +.Fn dispatch_source_get_data +indicates which of the events in the +.Fa mask +were observed. +.Pp +.Vt DISPATCH_SOURCE_TYPE_WRITE +.Pp +Sources of this type monitor file descriptors for available write buffer space. +The +.Fa handle +is the file descriptor (int) to monitor and the +.Fa mask +is unused and should be zero. +.Pp +Users of this source type are strongly encouraged to perform non-blocking I/O +and handle any truncated reads or error conditions that may occur.

+.Dt KQUEUE 2 +.Os +.Sh NAME +.Nm kqueue , +.Nm kevent +.Nd kernel event notification mechanism +.Sh SYNOPSIS +.In sys/types.h +.In sys/event.h +.In sys/time.h +.Ft int +.Fn kqueue "void" +.Ft int +.Fn kevent "int kq" "const struct kevent *changelist" "int nchanges" "struct kevent *eventlist" "int nevents" "const struct timespec *timeout" +.Fn EV_SET "&kev" ident filter flags fflags data udata +.Sh DESCRIPTION +The +.Fn kqueue +system call +provides a generic method of notifying the user when an event +happens or a condition holds, based on the results of small +pieces of kernel code termed filters. +A kevent is identified by the (ident, filter) pair; there may only +be one unique kevent per kqueue. +.Pp +The filter is executed upon the initial registration of a kevent +in order to detect whether a preexisting condition is present, and is also +executed whenever an event is passed to the filter for evaluation. +If the filter determines that the condition should be reported, +then the kevent is placed on the kqueue for the user to retrieve. +.Pp +The filter is also run when the user attempts to retrieve the kevent +from the kqueue. +If the filter indicates that the condition that triggered +the event no longer holds, the kevent is removed from the kqueue and +is not returned. +.Pp +Multiple events which trigger the filter do not result in multiple +kevents being placed on the kqueue; instead, the filter will aggregate +the events into a single struct kevent. +Calling +.Fn close +on a file descriptor will remove any kevents that reference the descriptor. +.Pp +The +.Fn kqueue +system call +creates a new kernel event queue and returns a descriptor. +The queue is not inherited by a child created with +.Xr fork 2 . +However, if +.Xr rfork 2 +is called without the +.Dv RFFDG +flag, then the descriptor table is shared, +which will allow sharing of the kqueue between two processes. +.Pp +The +.Fn kevent +system call +is used to register events with the queue, and return any pending +events to the user. +The +.Fa changelist +argument +is a pointer to an array of +.Va kevent +structures, as defined in +.In sys/event.h . +All changes contained in the +.Fa changelist +are applied before any pending events are read from the queue. +The +.Fa nchanges +argument +gives the size of +.Fa changelist . +The +.Fa eventlist +argument +is a pointer to an array of kevent structures. +The +.Fa nevents +argument +determines the size of +.Fa eventlist . +When +.Fa nevents +is zero, +.Fn kevent +will return immediately even if there is a +.Fa timeout +specified unlike +.Xr select 2 . +If +.Fa timeout +is a non-NULL pointer, it specifies a maximum interval to wait +for an event, which will be interpreted as a struct timespec. +If +.Fa timeout +is a NULL pointer, +.Fn kevent +waits indefinitely. +To effect a poll, the +.Fa timeout +argument should be non-NULL, pointing to a zero-valued +.Va timespec +structure. +The same array may be used for the +.Fa changelist +and +.Fa eventlist . +.Pp +The +.Fn EV_SET +macro is provided for ease of initializing a +kevent structure. +.Pp +The +.Va kevent +structure is defined as: +.Bd -literal +struct kevent { + uintptr_t ident; /* identifier for this event */ + short filter; /* filter for event */ + u_short flags; /* action flags for kqueue */ + u_int fflags; /* filter flag value */ + intptr_t data; /* filter data value */ + void *udata; /* opaque user data identifier */ +}; +.Ed +.Pp +The fields of +.Fa struct kevent +are: +.Bl -tag -width XXXfilter +.It ident +Value used to identify this event. +The exact interpretation is determined by the attached filter, +but often is a file descriptor. +.It filter +Identifies the kernel filter used to process this event. +The pre-defined +system filters are described below. +.It flags +Actions to perform on the event. +.It fflags +Filter-specific flags. +.It data +Filter-specific data value. +.It udata +Opaque user-defined value passed through the kernel unchanged. +.El +.Pp +The +.Va flags +field can contain the following values: +.Bl -tag -width XXXEV_ONESHOT +.It EV_ADD +Adds the event to the kqueue. +Re-adding an existing event +will modify the parameters of the original event, and not result +in a duplicate entry. +Adding an event automatically enables it, +unless overridden by the EV_DISABLE flag. +.It EV_ENABLE +Permit +.Fn kevent +to return the event if it is triggered. +.It EV_DISABLE +Disable the event so +.Fn kevent +will not return it. +The filter itself is not disabled. +.It EV_DISPATCH +Disable the event source immediately after delivery of an event. +See +.Dv EV_DISABLE +above. +.It EV_DELETE +Removes the event from the kqueue. +Events which are attached to +file descriptors are automatically deleted on the last close of +the descriptor. +.It EV_RECEIPT +This flag is useful for making bulk changes to a kqueue without draining +any pending events. +When passed as input, it forces +.Dv EV_ERROR +to always be returned. +When a filter is successfully added the +.Va data +field will be zero. +.It EV_ONESHOT +Causes the event to return only the first occurrence of the filter +being triggered. +After the user retrieves the event from the kqueue, +it is deleted. +.It EV_CLEAR +After the event is retrieved by the user, its state is reset. +This is useful for filters which report state transitions +instead of the current state. +Note that some filters may automatically +set this flag internally. +.It EV_EOF +Filters may set this flag to indicate filter-specific EOF condition. +.It EV_ERROR +See +.Sx RETURN VALUES +below. +.El +.Pp +The predefined system filters are listed below. +Arguments may be passed to and from the filter via the +.Va fflags +and +.Va data +fields in the kevent structure. +.Bl -tag -width EVFILT_SIGNAL +.It EVFILT_READ +Takes a descriptor as the identifier, and returns whenever +there is data available to read. +The behavior of the filter is slightly different depending +on the descriptor type. +.Pp +.Bl -tag -width 2n +.It Sockets +Sockets which have previously been passed to +.Fn listen +return when there is an incoming connection pending. +.Va data +contains the size of the listen backlog. +.Pp +Other socket descriptors return when there is data to be read, +subject to the +.Dv SO_RCVLOWAT +value of the socket buffer. +This may be overridden with a per-filter low water mark at the +time the filter is added by setting the +NOTE_LOWAT +flag in +.Va fflags , +and specifying the new low water mark in +.Va data . +On return, +.Va data +contains the number of bytes of protocol data available to read. +.Pp +If the read direction of the socket has shutdown, then the filter +also sets EV_EOF in +.Va flags , +and returns the socket error (if any) in +.Va fflags . +It is possible for EOF to be returned (indicating the connection is gone) +while there is still data pending in the socket buffer. +.It Vnodes +Returns when the file pointer is not at the end of file. +.Va data +contains the offset from current position to end of file, +and may be negative. +.It "Fifos, Pipes" +Returns when the there is data to read; +.Va data +contains the number of bytes available. +.Pp +When the last writer disconnects, the filter will set EV_EOF in +.Va flags . +This may be cleared by passing in EV_CLEAR, at which point the +filter will resume waiting for data to become available before +returning. +.It "BPF devices" +Returns when the BPF buffer is full, the BPF timeout has expired, or +when the BPF has +.Dq immediate mode +enabled and there is any data to read; +.Va data +contains the number of bytes available. +.El +.It EVFILT_WRITE +Takes a descriptor as the identifier, and returns whenever +it is possible to write to the descriptor. +For sockets, pipes +and fifos, +.Va data +will contain the amount of space remaining in the write buffer. +The filter will set EV_EOF when the reader disconnects, and for +the fifo case, this may be cleared by use of EV_CLEAR. +Note that this filter is not supported for vnodes or BPF devices. +.Pp +For sockets, the low water mark and socket error handling is +identical to the EVFILT_READ case. +.It EVFILT_VNODE +Takes a file descriptor as the identifier and the events to watch for in +.Va fflags , +and returns when one or more of the requested events occurs on the descriptor. +The events to monitor are: +.Bl -tag -width XXNOTE_RENAME +.It NOTE_DELETE +The +.Fn unlink +system call +was called on the file referenced by the descriptor. +.It NOTE_WRITE +A write occurred on the file referenced by the descriptor. +.It NOTE_EXTEND +The file referenced by the descriptor was extended. +.It NOTE_ATTRIB +The file referenced by the descriptor had its attributes changed. +.It NOTE_LINK +The link count on the file changed. +.It NOTE_RENAME +The file referenced by the descriptor was renamed. +.El +.Pp +On return, +.Va fflags +contains the events which triggered the filter. +.It EVFILT_SIGNAL +Takes the signal number to monitor as the identifier and returns +when the given signal is delivered to the process. +This overrides the +.Fn signal +and +.Fn sigaction +facilities, and has a higher precedence. +The filter will record +all attempts to deliver a signal to a process, even if the signal has +been marked as SIG_IGN. +.Va data +returns the number of times the signal has occurred since the last call to +.Fn kevent . +This filter automatically sets the EV_CLEAR flag internally. +.It EVFILT_TIMER +Establishes an arbitrary timer identified by +.Va ident . +When adding a timer, +.Va data +specifies the timeout period in milliseconds. +The timer will be periodic unless EV_ONESHOT is specified. +On return, +.Va data +contains the number of times the timeout has expired since the last call to +.Fn kevent . +This filter automatically sets the EV_CLEAR flag internally. +There is a system wide limit on the number of timers +which is controlled by the +.Va kern.kq_calloutmax +sysctl. +.It Dv EVFILT_USER +Establishes a user event identified by +.Va ident +which is not assosicated with any kernel mechanism but is triggered by +user level code. +The lower 24 bits of the +.Va fflags +may be used for user defined flags and manipulated using the following: +.Bl -tag -width XXNOTE_FFLAGSMASK +.It Dv NOTE_FFNOP +Ignore the input +.Va fflags . +.It Dv NOTE_FFAND +Bitwise AND +.Va fflags . +.It Dv NOTE_FFOR +Bitwise OR +.Va fflags . +.It Dv NOTE_COPY +Copy +.Va fflags . +.It Dv NOTE_FFCTRLMASK +Control mask for +.Va fflags . +.It Dv NOTE_FFLAGSMASK +User defined flag mask for +.Va fflags . +.El +.Pp +A user event is triggered for output with the following: +.Bl -tag -width XXNOTE_FFLAGSMASK +.It Dv NOTE_TRIGGER +Cause the event to be triggered. +.El +.Pp +On return, +.Va fflags +contains the users defined flags in the lower 24 bits. +.El +.Sh RETURN VALUES +The +.Fn kqueue +system call +creates a new kernel event queue and returns a file descriptor. +If there was an error creating the kernel event queue, a value of -1 is +returned and errno set. +.Pp +The +.Fn kevent +system call +returns the number of events placed in the +.Fa eventlist , +up to the value given by +.Fa nevents . +If an error occurs while processing an element of the +.Fa changelist +and there is enough room in the +.Fa eventlist , +then the event will be placed in the +.Fa eventlist +with +.Dv EV_ERROR +set in +.Va flags +and the system error in +.Va data . +Otherwise, +.Dv -1 +will be returned, and +.Dv errno +will be set to indicate the error condition. +If the time limit expires, then +.Fn kevent +returns 0. +.Sh ERRORS +The +.Fn kqueue +system call fails if: +.Bl -tag -width Er +.It Bq Er ENOMEM +The kernel failed to allocate enough memory for the kernel queue. +.It Bq Er EMFILE +The per-process descriptor table is full. +.It Bq Er ENFILE +The system file table is full. +.El +.Pp +The +.Fn kevent +system call fails if: +.Bl -tag -width Er +.It Bq Er EACCES +The process

create and submit work items to a thread pool. +.Pp +The user may create multiple work queues of different priority and +manually overcommit the available resources. +.Pp +.Fn pthread_workqueue_init_np +allocates and initializes the thread workqueue subsystem. +.Pp +.Fn pthread_workqueue_create_np +creates a new thread workqueue with the attributes given by +.Fa attr . +If +.Fa attr +is NULL then the default attributes are used. +A workqueue handle is returned in the +.Fa workqp +parameter. +.Pp +Thread workqueue attributes are used to specify parameters to +.Fn pthread_workqueue_create_np . +One attribute object can be used in multiple calls to +.Fn pthread_workqueue_create_np , +with or without modifications between calls. +.Pp +.Fn pthread_workqueue_additem_np +is used to submit work items to the thread pool specified by +.Fa workq +parameter. +The work item function and function argument are given by +.Fa workitem_func +and +.Fa workitem_arg . +The work item handle is returned in +.Fa itemhandlep . +.Pp +The +.Fn pthread_workqueue_attr_init_np +function initializes +.Fa attr +with all the default thread workqueue attributes. +.Pp +The +.Fn pthread_workqueue_attr_destroy_np +function destroys +.Fa attr . +.Pp +The +.Fn pthread_workqueue_attr_set*_np +functions set the attribute that corresponds to each function name. +.Fn pthread_workqueue_attr_setovercommit_np +can be used to set the overcommit flag. +If the overcommit flag is set then more threads will be started, if +needed, which may overcommit the physical resources of the system. +.Fn pthread_workqueue_attr_setqueuepriority_np +sets the queue priority attribute of the thread work queue and must be +set to one of the following values: +.Bl -tag -width "Va WORKQ_DEFAULT_PRIOQUEUE" +.It Va WORKQ_HIGH_PRIOQUEUE +Work items in the queue with this attribute will be given higher priority by +the thread scheduler. +.It Va WORKQ_DEFAULT_PRIOQUEUE +Work items in the queue with this attribute are given the default +priority. +.It Va WORKQ_LOW_PRIOQUEUE +Work items in the queue with this attribute will be given lower priority +by the thread scheduler. +.El +.Pp +The +.Fn pthread_workqueue_attr_get*_np +functions copy the value of the attribute that corresponds to each function name +to the location pointed to by the second function parameter. +.Sh RETURN VALUES +If successful, these functions return 0. +Otherwise, an error number is returned to indicate the error. +.Sh ERRORS +The +.Fn pthread_workqueue_init_np +function will
