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.

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.
