Hi all,
I have a question about pthread_join(). I would like my main thread
(i.e. the one that created all the new threads) to obtain the exit
code of the other threads..
For example: I can do this easily in NT.
main()
{
HANDLE threads[20];
// Create # of threads here ..
for (int i=0; i < 20; i++) {
threads[i] = CreateThread(...);
}
// This function will returns when one of the threads exit!
WaitForMulitipleObjects(20,threads,FALSE,..);
}
How can I do the same thing in Pthread ???? I could probably do
something like:
main()
{
pthread_t threads[20];
for (int i=0; i < 20; i++) {
threads[i] = pthread_create(...);
}
// don't think this will work because, it is joining
// threads[0] and then threads[1] ....
// what happen if threads[5] exit ? I want to know
// immediately ...
for (int i=0; i < 20; i++) {
pthread_join (threads[i], status);
}
}
Any suggestion and discussion is greately appreciated ...
Thanks..
later,
