+@code{_SC_SYMLOOP} by @code{sysconf}. In fact, the @code{sysconf}

+
+@comment stdlib.h
+@comment GNU
+@deftypefun {char *} canonicalize_file_name (const char *@var{name})
+
+The @code{canonicalize_file_name} function returns the absolute name of
+the file named by @var{name} which contains no @code{.}, @code{..}
+components nor any repeated path separators (@code{/}) or symlinks. The
+result is passed back as the return value of the function in a block of
+memory allocated with @code{malloc}. If the result is not used anymore
+the memory should be freed with a call to @code{free}.
+
+In any of the path components except the last one is missing the
+function returns a NULL pointer. This is also what is returned if the
+length of the path reaches or exceeds @code{PATH_MAX} characters. In
+any case @code{errno} is set accordingly.
+
+@table @code
+@item ENAMETOOLONG
+The resulting path is too long. This error only occurs on systems which
+have a limit on the file name length.
+
+@item EACCES
+At least one of the path components is not readable.
+
+@item ENOENT
+The input file name is empty.

+At least one of the path components does not exist.

+@code{canonicalize_file_name} in that the user has to provide the buffer
+where the result is placed in.
+
+@comment stdlib.h
+@comment XPG
+@deftypefun {char *} realpath (const char *restrict @var{name}, char *restrict @var{resolved})
+
+The @code{realpath} function behaves just like
+@code{canonicalize_file_name} but instead of allocating a buffer for the
+result it is placed in the buffer pointed to by @var{resolved}.
+
+One other difference is that the buffer @var{resolved} will contain the
+part of the path component which does not exist or is not readable if
+the function returns @code{NULL} and @code{errno} is set to
+@code{EACCES} or @code{ENOENT}.
+
+This function is declared in @file{stdlib.h}.
+@end deftypefun
+
+The advantage of using this function is that it is more widely
+available. The drawback is that it reports failures for long path on
+systems which have no limits on the file name length.

+@section Complete Context Control
+
+The Unix standard one more set of function to control the execution path
+and these functions are more powerful than those discussed in this
+chapter so far. These function were part of the original @w{System V}
+API and by this route were added to the Unix API. Beside on branded
+Unix implementations these interfaces are not widely available. Not all
+platforms and/or architectures the GNU C Library is available on provide
+this interface. Use @file{configure} to detect the availability.
+
+Similar to the @code{jmp_buf} and @code{sigjmp_buf} types used for the
+variables to contain the state of the @code{longjmp} functions the
+interfaces of interest here have an appropriate type as well. Objects
+of this type are normally much larger since more information is
+contained. The type is also used in a few more places as we will see.
+The types and functions described in this section are all defined and
+declared respectively in the @file{ucontext.h} header file.
+
+@comment ucontext.h
+@comment SVID
+@deftp {Data Type} ucontext_t
+
+The @code{ucontext_t} type is defined as a structure with as least the
+following elements:
+
+@table @code
+@item ucontext_t *uc_link
+This is a pointer to the next context structure which is used if the
+context described in the current structure returns.
+
+@item sigset_t uc_sigmask
+Set of signals which are blocked when this context is used.
+
+@item stack_t uc_stack
+Stack used for this context. The value need not be (and normally is
+not) the stack pointer. @xref{Signal Stack}.
+
+@item mcontext_t uc_mcontext
+This element contains the actual state of the process. The
+@code{mcontext_t} type is also defined in this header but the definition
+should be treated as opaque. Any use of knowledge of the type makes
+applications less portable.
+
+@end table
+@end deftp
+
+Objects of this type have to be created by the user. The initialization
+and modification happens through one of the following functions:
+
+@comment ucontext.h
+@comment SVID
+@deftypefun int getcontext (ucontext_t *@var{ucp})
+The @code{getcontext} function initializes the variable pointed to by
+@var{ucp} with the context of the calling thread. The context contains
+the content of the registers, the signal mask, and the current stack.
+Executing the contents would start at the point where the
+@code{getcontext} call just returned.
+
+The function returns @code{0} if succesful. Otherwise it returns
+@code{-1} and sets @var{errno} accordingly.
+@end deftypefun
+
+The @code{getcontext} function is similar to @code{setjmp} but it does
+not provide an indication of whether the function returns for the first
+time or whether the initialized context was used and the execution is
+resumed at just that point. If this is necessary the user has to take
+determine this herself. This must be done carefully since the context
+contains registers which might contain register variables. This is a
+good situation to define variables with @code{volatile}.
+
+Once the context variable is initialized it can be used as is or it can
+be modified. The latter is normally done to implement co-routines or
+similar constructs. The @code{makecontext} function is what has to be
+used to do that.
+
+@comment ucontext.h
+@comment SVID
+@deftypefun void makecontext (ucontext_t *@var{ucp}, void (*@var{func}) (void), int @var{argc}, @dots{})
+
+The @var{ucp} parameter passed to the @code{makecontext} shall be
+initialized by a call to @code{getcontext}. The context will be
+modified to in a way so that if the context is resumed it will start by
+calling the function @code{func} which gets @var{argc} integer arguments
+passed. The integer arguments which are to be passed should follow the
+@var{argc} parameter in the call to @code{makecontext}.
+
+Before the call to this function the @code{uc_stack} and @code{uc_link}
+element of the @var{ucp} structure should be initialized. The
+@code{uc_stack} element describes the stack which is used for this
+context. No two contexts which are used at the same time should use the
+same memory region for a stack.
+
+The @code{uc_link} element of the object pointed to by @var{ucp} should
+be a pointer to the context to be executed when the function @var{func}
+returns or it should be a null pointer. See @code{setcontext} for more
+information about the exact use.
+@end deftypefun
+
+While allocating the memory for the stack one has to be careful. Most
+modern processors keep track of whether a certain memory region is
+allowed to contain code which is executed or not. Data segments and
+heap memory is normally not tagged to allow this. The result is that
+programs would fail. Examples for such code include the calling
+sequences the GNU C compiler generates for calls to nested functions.
+Safe ways to allocate stacks correctly include using memory on the
+original threads stack or explicitly allocate memory tagged for
+execution using (@pxref{Memory-mapped I/O}).
+
+@strong{Compatibility note}: The current Unix standard is very imprecise
+about the way the stack is allocated. All implementations seem to agree
+that the @code{uc_stack} element must be used but the values stored in
+the elements of the @code{stack_t} value are unclear. The GNU C library
+and most other Unix implementations require the @code{ss_sp} value of
+the @code{uc_stack} element to point to the base of the memory region
+allocated for the stack and the size of the memory region is stored in
+@code{ss_size}. There are implements out there which require
+@code{ss_sp} to be set to the value the stack pointer will have (which
+can depending on the direction the stack grows be different). This
+difference makes the @code{makecontext} function hard to use and it
+requires detection of the platform at compile time.
+
+@comment ucontext.h
+@comment SVID
+@deftypefun int setcontext (const ucontext_t *@var{ucp})
+
+The @code{setcontext} function restores the context described by
+@var{ucp}. The context is not modified and can be reused as often as
+wanted.
+
+If the context was created by @code{getcontext} execution resumes with
+the registers filled with the same values and the same stack as if the
+@code{getcontext} call just returned.
+
+If the context was modified with a call to @code{makecontext} execution
+continues with the function passed to @code{makecontext} which gets the
+specified parameters passed. If this function returns execution is
+resumed in the context which was referenced by the @code{uc_link}
+element of the context structure passed to @code{makecontext} at the
+time of the call. If @code{uc_link} was a null pointer the application
+terminates in this case.
+
+Since the context contains information about the stack no two threads
+should use the same context at the same time. The result in most cases
+would be disastrous.
+
+The @code{setcontext} function does not return unless an error occurred
+in which case it returns @code{-1}.
+@end deftypefun
+
+The @code{setcontext} function simply replaces the current context with
+the one described by the @var{ucp} parameter. This is often useful but
+there are situations where the current context has to be preserved.
+
+@comment ucontext.h
+@comment SVID
+@deftypefun int swapcontext (ucontext_t *restrict @var{oucp}, const ucontext_t *restrict @var{ucp})
+
+The @code{swapcontext} function is similar to @code{setcontext} but
+instead of just replacing the current context the latter is first saved
+in the object pointed to by @var{oucp} as if this was a call to
+@code{getcontext}. The saved context would resume after the call to
+@code{swapcontext}.
+
+Once the current context is saved the context described in @var{ucp} is
+installed and execution continues as described in this context.
+
+If @code{swapcontext} succeeds the function does not return unless the
+context @var{oucp} is used without prior modification by
+@code{makecontext}. The return value in this case is @code{0}. If the
+function fails it returns @code{-1} and set @var{errno} accordingly.
+@end deftypefun
+
+@heading Example for SVID Context Handling
+
+The easiest way to use the context handling functions is as a
+replacement for @code{setjmp} and @code{longjmp}. The context contains
+on most platforms more information which might lead to less surprises
+but this also means using these functions is more expensive (beside
+being less portable).
+
+@smallexample
+int
+random_search (int n, int (*fp) (int, ucontext_t *))
+@{
+ volatile int cnt = 0;
+ ucontext_t uc;
+
+ /* @r{Safe current context.} */
+ if (getcontext (&uc) < 0)
+ return -1;
+
+ /* @r{If we have not tried @var{n} times try again.} */
+ if (cnt++ < n)
+ /* @r{Call the function with a new random number}
+ @r{and the context}. */
+ if (fp (rand (), &uc) != 0)
+ /* @r{We found what we were looking for.} */
+ return 1;
+
+ /* @r{Not found.} */
+ return 0;
+@}
+@end smallexample
+
+Using contexts in such a way enables emulating exception handling. The
+search functions passed in the @var{fp} parameter could be very large,
+nested, and complex which would make it complicated (or at least would
+require a lot of code) to leave the function with an error value which
+has to be passed down to the caller. By using the context it is
+possible to leave the search function in one step and allow restarting
+the search which also has the nice side effect that it can be
+significantly faster.
+
+Something which is harder to implement with @code{setjmp} and
+@code{longjmp} is to switch temporarily to a different execution path
+and then resume where execution was stopped.
+
+@smallexample
+@include swapcontext.c.texi
+@end smallexample
+
+This an example how the context functions can be used to implement
+co-routines or cooperative multi-threading. All that has to be done is
+to call every once in a while @code{swapcontext} to continue running a
+different context. It is not allowed to do the context switching from
+the signal handler directly since neither @code{setcontext} nor
+@code{swapcontext} are functions which can be called from a signal
+handler. But setting a variable in the signal handler and checking it
+in the body of the functions which are executed. Since
+@code{swapcontext} is saving the current context it is possible to have
+multiple different scheduling points in the code. Execution will always
+resume where it was left.
