pthread_equal - compare thread IDs
int pthread_equal(pthread_t t1, pthread_t t2);
This function shall compare the thread IDs t1 and t2.
The pthread_equal() function shall return a non-zero value if t1 and t2 are equal; other-
wise, zero shall be returned.
If either t1 or t2 are not valid thread IDs, the behavior is undefined.
No errors are defined.
The pthread_equal() function shall not return an error code of [EINTR].
The following sections are informative.
Implementations may choose to define a thread ID as a structure. This allows additional
flexibility and robustness over using an int. For example, a thread ID could include a
sequence number that allows detection of "dangling IDs" (copies of a thread ID that has
been detached). Since the C language does not support comparison on structure types, the
pthread_equal() function is provided to compare thread IDs.
