NAME
pthread_equal - compare thread IDs

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.

CONFORMING TO

NOTES
