+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
+2006, 2007, 2008 Free Software Foundation, Inc.
+
+ This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+ Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package. The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system.
+
+ Running `configure' might take a while. While running, it prints
+ some messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+ 6. Often, you can also type `make uninstall' to remove the installed
+ files again.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you can use GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory. After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+ On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor. Like
+this:
+
+ ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CPP="gcc -E" CXXCPP="g++ -E"
+
+ This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+ By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Particular systems
+==================
+
+ On HP-UX, the default C compiler is not ANSI C compatible. If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+ ./configure CC="cc -Ae"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+ On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file. The option `-nodtk' can be used as
+a workaround. If GNU CC is not installed, it is therefore recommended
+to try
+
+ ./configure CC="cc"
+
+and if that doesn't work, try
+
+ ./configure CC="cc -nodtk"
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on. Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+ Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug. Until the bug is fixed you can use this workaround:
+
+ CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+ Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+ Print a summary of the options unique to this package's
+ `configure', and exit. The `short' variant lists options used
+ only in the top level, while the `recursive' variant lists options
+ also present in any nested packages.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+ Use DIR as the installation prefix. *Note Installation Names::
+ for more details, including other options available for fine-tuning
+ the installation locations.
+
+`--no-create'
+`-n'
+ Run the configure checks, but stop before creating any output
+ files.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+ DRAFT FOR REVIEW
+ The X Resource Extension
+ Version 1.2
+ Rami Ylimäki
+ rami.ylimaki@vincit.fi
+
+ ❧❧❧❧❧❧❧❧❧❧❧
+
+1. Introduction
+
+The protocol description of X Resource Extension version 1.1 has been
+either lost or has never been written. This specification documents
+version 1.0 based on reverse engineered library and server
+code. Version 1.1 has been accidentally released from the version
+control and while it doesn't have differences to version 1.0, this
+version is labeled 1.2 in order to remove the risk of confusion. In
+addition to the 1.0 description, this document introduces a new 1.2
+version of the extension.
+
+Version 1.2 is a minor release and therefore the changes are
+compatible with the previous version. Main enhancements over version
+1.0 are:
+
+- Client identification is now possible. For example, servers
+ supporting version 1.2 may report PID of local clients.
+
+- Size of any resource can be queried from the server. Servers may not
+ necessarily support size calculation for every resource. However,
+ clients have now at least the chance to let the server do resource
+ size estimation for them.
+
+ ❧❧❧❧❧❧❧❧❧❧❧
+
+2. Notations used in this document
+
+Notation for data types and requests follows the guidelines set in
+sections 2-4 of X Window System Protocol standard.
+
+ ❧❧❧❧❧❧❧❧❧❧❧
+
+3. Interoperability between version 1.1 and 1.2
+
+Version 1.2 only introduces two new requests. However, these requests
+could be seen as generalized versions of existing requests. Even
+though we aren't deprecating any old requests, libraries could
+implement some old requests using the new ones.
+
+The new XResQueryClientIds request could be used instead of
+XResQueryClients.
+
+The new XResQueryResourceBytes request could be used instead of
+XResQueryClientPixmapBytes.
+
+Using the old requests is still acceptable because we don't want to
+change the semantics of existing requests between version 1.1 and 1.2.
+
+ ❧❧❧❧❧❧❧❧❧❧❧
+
+4. Data types
+
+4.1 Types in version 1.0
+
+CLIENTXIDRANGE [ resource_base: CARD32
+ resource_mask: CARD32 ]
+
+This type is used for reply of XResQueryClients in version 1.1. It
+represents the range of resource allocated for a client and can be
+also used for client identification.
+
+resource_base
+ First resource ID reserved for a client. Used also to identify the
+ clients themselves.
+resource_mask
+ Mask that can be used to identify a client from some resource
+ ID. Just zero the bits indicated by this mask from any resource ID
+ to identify the client that owns the resource.
+
+CLIENTXID [ client: XID ]
+
+This type identifies a single client by a resource owned by that
+client or by the first resource ID allocated for the client
+(resource_base of CLIENTXIDRANGE). Whenever a resource ID is used, it
+is masked by resource_mask of CLIENTXIDRANGE to find out the client
+that owns the resource.
+
+CLIENTRESOURCETYPECOUNT [ resource_type: ATOM
+ count: CARD32 ]
+
+This type is used for reply of XResQueryClientResources in version
+1.1. It represents the number of certain type of resources that are
+owned by some client.
+
+resource_type
+ Atom specifying the type of a resource.
+count
+ Number of resources of the given type owned by a client.
+
+4.2 Types in version 1.2
+
+4.2.1 Types used by XResQueryClientIds
+
+CLIENTIDMASK { ClientXid = 0x1, LocalClientPid = 0x2 }
+
+A bitmask specifying a client identification method. Currently only
+the PID of local clients is supported in the form of
+LocalClientPid. ClientXid is provided for backward compatibility with
+version 1.0 so that the new 1.2 requests (XResQueryClientIds) can be
+used in place of the older ones (XResQueryClients).
+
+CLIENTIDSPEC [ client: CLIENTXID or None
+ mask: SETofCLIENTIDMASK or None ]
+
+A data structure for selecting client IDs.
+
+client
+ ID of a resource allocated for some client. Only the part
+ identifying a client is actually used. The resource_base of
+ CLIENTXIDRANGE can be used if the client doesn't own any
+ resources. However, any resource ID is accepted because that makes
+ identifying the owners of existing resources easy. The null
+ resource None can be used to select all clients.
+mask
+ Collection of identification methods that should be applied on the
+ client. The special value None can be used to apply all supported
+ identification methods.
+
+CLIENTIDVALUE [ spec: CLIENTIDSPEC
+ length: CARD32
+ value: LISTofCARD32 ]
+
+A data structure specifying a single client ID.
+
+spec
+ A unique identifier for a specific ID of some client. Wildcards
+ such as None and bitmask unions aren't allowed. The data structure
+ must always identify a single client and single ID type. However,
+ the client doesn't have to be specified as the resource_base of
+ CLIENTXIDRANGE and can be any resource owned by the client.
+length
+ Specifies the length of an ID in units of CARD32. The length
+ depends on the ID type. In version 1.2 the lengths are 0 for
+ ClientXid and 4 for LocalClientPid. The length of ClientXid is 0
+ because that is already stored in the spec field.
+value
+ Actual ID data. In version 1.2 this is missing for ClientXid and
+ consists of a single CARD32 for LocalClientPid.
+
+4.2.2 Types used by XResQueryResourceBytes
+
+To better understand how resources are related to each other, it's
+useful to introduce the concepts of main resource and cross
+reference. By main resource we just mean a normal resource that has a
+valid XID. By cross reference we mean a resource that is used by some
+other resource.
+
+The same resource may have both of these roles depending on the
+context. For example, there could be an ordinary pixmap resource. When
+we talk about this resource in isolation the term main resource is
+used. We call the exact same resource a cross reference when we are
+concentrating on some higher level resource, such as window or
+graphics context, that is using the lower level resource. Cross
+references may also be internal server resources that don't have a
+valid XID.
+
+RESOURCEIDSPEC [ resource: XID or None
+ type: ATOM or None/AnyPropertyType ]
+
+A data structure for selecting or identifying resources. The
+interpretation of fields changes depending on the context. The
+differences in interpretation are described below.
+
+resource
+ An XID of a resource. The null resource None can be used to select
+ all resources matching some type if the data structure is used in
+ XResQueryResourceBytes request. The null resource None can be used
+ to mark private server resources if the data structure is used in
+ a cross reference of XResQueryResourceBytes reply.
+type
+ An atom identifying the resource type. The null atom
+ None/AnyPropertyType can be used to select all resource types
+ matching some resource ID if the data structure is used in
+ XResQueryResourceBytes request.
+
+RESOURCESIZESPEC [ spec: RESOURCEIDSPEC
+ bytes: CARD32
+ ref_count: CARD32
+ use_count: CARD32 ]
+
+A data structure specifying the size of a single resource.
+
+spec
+ Uniquely identifies a single resource. Wildcards such as None and
+ AnyPropertyType aren't allowed for main resources. In cross
+ references, None is used to mark internal server resources.
+bytes
+ Number of bytes allocated for the resource. The size of a resource
+ is never divided by a reference count. This is the number of bytes
+ released in server when there are no more references left to the
+ resource.
+ref_count
+ Number of total users of the resource. Typically the reference
+ count is 1 but for pixmaps and other resources used from different
+ contexts the count may be larger.
+use_count
+ Number of times the resource is used by some other resource. For
+ main resources this is typically 1, because a resource doesn't
+ usually use itself recursively. For cross references this is the
+ number of times the resource is used and is also 1 usually.
+
+RESOURCESIZEVALUE [ size: RESOURCESIZESPEC
+ num_cross_references: CARD32
+ cross_references: LISTofRESOURCESIZESPEC ]
+
+A data structure specifying sizes of cross references to other
+resources in addition to the main resource size.
+
+size
+ Size of a main resource.
+num_cross_references
+ Number of cross references to other resources from the main
+ resource. Currently resources can only have pixmaps as cross
+ references but this can be extended to other types in the
+ future. For simple resources this field is therefore 0 and the
+ cross_references list is missing.
+cross_references:
+ Size specifications for cross references. Note that cross
+ references may contain resources that don't have a valid XID. For
+ example, a DRI2 drawable might have a cross reference to a private
+ pixmap that is used internally in the server only. These private
+ cross references are contained in this list also. This makes it
+ possible to emulate XResGetClientPixmapBytes with
+ XResGetResourceBytes.

+
+This request can be used to ask the number of resources owned by a

+
+client
+ An XID in the resource range of a client. This identifies the
+ client and not some specific resource.
+num_types
+ Number of different resource types owned by the client.
+types
+ A list of counts for each resource type.
+

+
+┌───
+ XResQueryClientPixmapBytes
+ client: CLIENTXID
+ ▶
+ bytes: CARD32
+ bytes_overflow: CARD32
+
+ Errors: Value
+└───
+
+This request is used to get the pixmap usage of some client. The
+returned number is a sum of memory usage of each pixmap that can be
+attributed to the given client. Ideally the server goes through all
+pixmaps and divides each pixmap size by the pixmap reference count to
+get a pixmap reference size. The reference size is then added to the
+returned sum if the client happens to be referencing that pixmap. In
+practice some pixmap references may be missed, because it would be too
+difficult to keep track of all pixmap references. However, the server
+will check the most important client resources that are using pixmaps
+and tries to estimate the pixmap usage as well as is possible. In
+other words, the server need only make a best-effort attempt to
+calculate resource source, so actual resource size may differ from
+that reported in practice.
+
+client
+ Identifies a client by an ID in its resource ID range.
+bytes:
+ Number of bytes attributed to pixmap references from the client
+ resources.
+bytes_overflow:
+ Higher order word for the bytes field in case the sum of pixmap
+ reference sizes doesn't fit in CARD32.
+
+A value error is generated if invalid resource or client XID is given
+in the request.

+5.2 Requests in version 1.2
+
+┌───
+ XResQueryClientIds
+ num_specs: CARD32
+ client_specs: LISTofCLIENTIDSPEC
+ ▶
+ num_ids: CARD32
+ client_ids: LISTofCLIENTIDVALUE
+
+ Errors: Value
+└───
+
+XResQueryClientIds can be used to identify a given set of clients with
+some identification method. The request sends a list of specifiers
+that select clients and identification methods to server. The server
+then tries to identify the chosen clients using the identification
+methods specified for each client. The server returns IDs for those
+clients that were successfully identified. It's not an error condition
+if some identification method couldn't be applied to a client. If the
+server is unable to identify some clients, they simply aren't included
+in the returned list.
+
+The request supports wildcards in the client specifications so that in
+the most general case all IDs of all clients can be queried with a
+single CLIENTIDSPEC.
+
+The CLIENTIDSPEC of request and CLIENTIDSPEC of CLIENTIDVALUE in reply
+usually match each other. For example, if a request selected a client
+by a resource ID owned by the client, then the client is identified by
+the same resource ID in the reply. This has been done so that it would
+be easy to identify an owner of some resource.
+
+However, the CLIENTIDSPEC of returned CLIENTIDVALUE never contains any
+wildcards. If the request used a wildcard to specify all clients in a
+single CLIENTIDSPEC, then the reply has expanded the wildcard and
+returns separate CLIENTIDVALUE records for each client. In this case
+wildcarded clients are identified by resource_base of CLIENTXIDRANGE.
+
+The LocalClientPid type of IDs are included in the reply list only if
+the client executing the request asked for it and was also a local
+client itself. It doesn't make sense for remote clients to ask PIDs of
+local clients.
+
+num_specs
+ Number of client ID specifications.
+client_specs
+ A list specifying identification methods for clients. Supports
+ multiple identification methods and clients in a single
+ specification. See CLIENTIDSPEC for details.
+num_ids
+ Number of IDs that were successfully determined. Can be different
+ from num_specs or even zero if the server didn't support any
+ identification methods for the given clients.
+client_ids
+ A list specifying ID information for successfully identified
+ clients. If wildcards were used in a single CLIENTIDSPEC of
+ client_specs, then multiple CLIENTIDVALUE records may be returned
+ for that CLIENTIDSPEC. See CLIENTIDVALUE for details.
+
+A Value error is returned if the request specifies an invalid client
+XID or invalid identification method type.
+
+┌───
+ XResQueryResourceBytes
+ client: CLIENTXID or None
+ num_specs: CARD32
+ resource_specs: LISTofRESOURCEIDSPEC
+ ▶
+ num_sizes: CARD32
+ sizes: LISTofRESOURCESIZEVALUE
+
+ Errors: Atom, Value
+└───
+
+XResQueryResourceBytes can be used to ask the sizes of resources from
+X server. The request sends a list of specifiers that selects
+resources for size calculation. The server tries to calculate the
+sizes of chosen resources and returns an estimate for a resource only
+if the size could be determined. It's not an error condition if a size
+couldn't be calculated. In that case the resources simply aren't
+included in the returned list.
+
+The request supports wildcards so that in the most general case sizes
+of all resources of all clients can be queried with a single
+RESOURCEIDSPEC. However, the reply has all wildcards expanded and
+reports a size of a single resource in each RESOURCESIZEVALUE.
+
+client
+ An ID of a client can be given to limit the query to resources of
+ that client. Just like in CLIENTIDSPEC, any resource ID can be
+ given to identify a client and None can be used if the query
+ shouldn't be limited to a specific client. Note that in some cases
+ this field is redundant because resource_specs already fully
+ determines which resources are selected. If the client ID doesn't
+ match the owner of any resource in resource_specs, no sizes are
+ returned and no error is generated.
+num_specs
+ Number of resource specifications.
+resource_specs
+ A list of resource specifications. Each specification can either
+ uniquely identify a single resource or multiple resources if
+ wildcarding is used. See RESOURCEIDSPEC for details.
+num_sizes
+ Number of resources whose size could be determined. Can be
+ different from num_specs or even zero if the server didn't support
+ size calculation for the given resources.
+sizes
+ A list of resource sizes. Each resource size is linked to a unique
+ resource. Wildcards are never used in the returned size
+ records. For example, it's not possible to receive a single
+ RESOURCESIZEVALUE that would specify the size of all pixmaps if
+ the sizes of pixmap type resources were asked. Instead, a single
+ RESOURCESIZEVALUE would be returned for each pixmap in that case.
+
+An Atom error is returned if the request specifies an invalid resource
+type. A Value error is returned if the request specifies an invalid
+XID for a client or a resource.
