I'd like to ask whether Linux provides an effective way to wait for
multiple thread's end. Using pthread_join, I can only wait for one
thread at a time. Microsoft provides WaitForMultipleObject for doing
this , how about glibc or POSIX?
Unix is very broken in this area. Everything is a file descriptor
except
everything that was designed after the initial release (IPC's either
Unix V
or posix). Yes Unix guys this sucks much - you don't even have a
common
way around the sucking select. Yes i know about kqueue.
But back to the question. The best is to write a small background
thread that
does nothing else then handle thread and process termination signals.
And
build a message passing algorithm on top of this. You can use a pipe
or so
as the base mechanism for the message queue.
