NAME

       pthread_equal - compare thread IDs

LIBRARY

       POSIX threads library (libpthread, -lpthread)

SYNOPSIS

       #include <pthread.h>

       int pthread_equal(pthread_t t1, pthread_t t2);

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.

STANDARDS

       POSIX.1-2008.

HISTORY

       POSIX.1-2001.

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.
