thrd_join —
#include <threads.h>
int
thrd_join(thrd_t thrd,
int *res);
thrd_join() function suspends the execution of the
current thread and waits for the thread indicated by
thrd to terminate and stores the exit status, as set by
a call to thrd_exit(3C), for that thread in
res, if res is non-null. The
thrd argument must be a member of the current process
and it cannot be detached. If thrd has already
terminated and another caller has not called
thrd_join() then the exit status will be returned to
the caller without blocking execution of the thread.
If multiple threads call thrd_join() on
the same thread, then both will be suspended until that thread terminates;
however, only one thread will return successfully and obtain the actual
status and the other will instead return with an error.
For additional information on the thread joining interfaces supported by the system, see pthread_join(3C) and thr_join(3C).
thrd_join() function
returns thrd_success and if res is a
non-null pointer, it will be filled in with the exit status of
thrd. If an error occurs, thrd_error
will be returned.
