pthread_equal(3T)              DG/UX 5.4R3.00              pthread_equal(3T)


NAME
       pthreadequal - compare thread IDs for equality

SYNOPSIS
       #include <pthread.h>

       int pthreadequal(pthreadt t1, pthreadt t2);

   where:
       t1     Thread ID #1
       t2     Thread ID #2

DESCRIPTION
       This function compares the thread IDs t1 and t2 for equality.  In
       fact, this is the only portable way to compare two thread IDs.

DIAGNOSTICS
   Returns
       The pthreadequal() function returns a non-zero value if t1 and t2
       are equal; otherwise it returns zero.

       If either t1 or t2 is not a valid thread ID, the behavior is
       undefined.  In the current DG/UX implementation, this case is
       impossible.

SEE ALSO
       pthreadcreate(3T), pthreadself(3T), dgpthreadgetlwpid(3T).

NOTES
       The only other portable operations on thread IDs are assignment and
       retrieval using a call to pthreadself().

       Refer to pthreadself(3T) NOTES for a more detailed discussion on
       proper use of thread IDs.
