PTHREAD_EQUAL(3)	   Linux Programmer's Manual	      PTHREAD_EQUAL(3)



NAME
       pthread_equal - compare thread IDs

SYNOPSIS
       #include <pthread.h>

       int pthread_equal(pthread_t t1, pthread_t t2);

       Compile and link with -pthread.

DESCRIPTION
       The pthread_equal() function compares two thread identifiers.

RETURN VALUE
       If  the	two  thread  IDs  are equal, pthread_equal() returns a nonzero
       value; otherwise, it returns 0.

ERRORS
       This function always succeeds.

ATTRIBUTES
       For  an	explanation  of	 the  terms  used   in	 this	section,   see

CONFORMING TO
       POSIX.1-2001, POSIX.1-2008.

NOTES
       The  pthread_equal() function is necessary because thread IDs should be
       considered opaque:  there  is  no  portable  way	 for  applications  to
       directly compare two pthread_t values.
