thrd_join — wait
for thread termination
#include
<threads.h>
int
thrd_join(thrd_t thrd,
int *res);
The
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).
Upon successful completion, the
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.
