pthread_equal(3) Library Functions Manual pthread_equal(3)

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 attributes(7).

Interface Attribute Value
pthread_equal () Thread safety MT-Safe

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.
