PTHREAD_EQUAL(P)	   POSIX Programmer's Manual	      PTHREAD_EQUAL(P)

PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the	 corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.

NAME
       pthread_equal - compare thread IDs

SYNOPSIS
       #include <pthread.h>

       int pthread_equal(pthread_t t1, pthread_t t2);

DESCRIPTION
       This function shall compare the thread IDs t1 and t2.

RETURN VALUE
       The pthread_equal() function shall return a non-zero value if t1 and t2
       are equal; otherwise, zero shall be returned.

       If either t1 or t2 are not valid thread IDs, the behavior is undefined.

ERRORS
       No errors are defined.

       The pthread_equal() function shall not return an error code of [EINTR].

       The following sections are informative.

EXAMPLES
       None.

APPLICATION USAGE
       None.

RATIONALE
       Implementations	may  choose to define a thread ID as a structure. This
       allows additional flexibility and robustness over  using	 an  int.  For
       example, a thread ID could include a sequence number that allows detecā€
       tion of "dangling IDs" (copies of a thread ID that has been  detached).
       Since  the  C  language does not support comparison on structure types,
       the pthread_equal() function is provided to compare thread IDs.

FUTURE DIRECTIONS
       None.
