Defined in header <threads.h>
int thrd_join( thrd_t thr, int *res );		(since C11)

Blocks the current thread until the thread identified by thr finishes execution.

If res is not a null pointer, the result code of the thread is put to the location pointed to by res.

The termination of the thread synchronizes-with the completion of this function.

The behavior is undefined if the thread was previously detached or joined by another thread.

Parameters

thr	-	identifier of the thread to join
res	-	location to put the result code to

Return value

thrd_success if successful, thrd_error otherwise.
