pthread_equal

POSIX threads library (libpthread, -lpthread)

#include <pthread.h>

int pthread_equal(pthread_t t1, pthread_t t2);

The pthread_equal() function compares two thread identifiers.

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

This function always succeeds.

For an explanation of the terms used in this section, see attributes(7).

POSIX.1-2008.

POSIX.1-2001.

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.
