SYNOPSIS
#include <pthread.h>
int pthread_equal(pthread_t t1, pthread_t t2);
Compile and link with -pthread.

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

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.
