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.

Attributes

Multithreading (see pthreads(7) )

The pthread_equal() function is thread-safe.

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.
