5. UNIX for Dummies Questions & Answers
Hi all,
Is it possible to do the following in Linux (kernel 2.6.x):
- A user-space thread goes to "sleep". Using any call/mechanism
- On a hardware generated interrupt, the Interrupt handler (ISR) "wakes" the sleeping user-thread.
I have seen wait_event() and wake_up() but it appears... (1 Reply)

thr_join(3C) Standard C Library Functions thr_join(3C)
NAME
thr_join - wait for thread termination
SYNOPSIS
cc -mt [ flag... ] file...[ library... ]
#include <thread.h>
int thr_join(thread_t thread, thread_t *departed, void **status);
DESCRIPTION
The thr_join() function suspends processing of the calling thread until the target thread completes. The thread argument must be a member
of the current process and cannot be a detached thread. See thr_create(3C).
If two or more threads wait for the same thread to complete, all will suspend processing until the thread has terminated, and then one
thread will return successfully and the others will return with an error of ESRCH. The thr_join() function will not block processing of the
calling thread if the target thread has already terminated.
If a thr_join() call returns successfully with a non-null status argument, the value passed to thr_exit(3C) by the terminating thread will
be placed in the location referenced by status.
If the target thread ID is 0, thr_join() finds and returns the status of a terminated undetached thread in the process. If no such thread
exists, it suspends processing of the calling thread until a thread for which no other thread is waiting enters that state, at which time
it returns successfully, or until all other threads in the process are either daemon threads or threads waiting in thr_join(), in which
case it returns EDEADLK. See NOTES.
If departed is not NULL, it points to a location that is set to the ID of the terminated thread if thr_join() returns successfully.
RETURN VALUES
If successful, thr_join() returns 0. Otherwise, an error number is returned to indicate the error.
ERRORS
EDEADLK A joining deadlock would occur, such as when a thread attempts to wait for itself, or the calling thread is waiting for any
thread to exit and only daemon threads or waiting threads exist in the process.
ESRCH No undetached thread could be found corresponding to the given thread ID.

NOTES
Using thr_join(3C) in the following syntax,
while (thr_join(0, NULL, NULL) == 0);
will wait for the termination of all non-daemon threads, excluding threads that are themselves waiting in thr_join().
