Name

pthread_equal — compare thread IDs

Synopsis

#include <pthread.h>
int pthread_equal( pthread_t t1,
  pthread_t t2);
 
[Note] Note

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.
