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

STANDARDS
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.
