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 non-zero 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.

SEE ALSO¶

pthread_create(3), pthread_self(3), pthreads(7)
