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.  

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.
