Hi

I have two threads, the main thread 'A' is responsible for message handling between a number of processes. When thread A gets a buffer full message, it should inform thread B and pass a pointer to the buffer which thread B will then process.

When thread B has finished it should inform thread A that it has finished.

How do I go about implementing this using posix threads using C on linux. I have looked at conditional variables, is this the way to go? . I'm not experienced in multi threaded programming and would like some advice on the best avenue to take.

Thanks

In a linux application I'm using pipes to pass information between threads. The idea behind using pipes is that I can wait for multiple pipes at once using poll(2).
