hey. i have 2 pthreads running.
one is a thread i have for handling keyboard interrupts. like if i press a 'q', it should message the other thread to stop what its doing, and if i press something else, it sends that char that i pressed to the other thread, where something else is done.
im not very sure how to do this.
while i have tried kill(pid, sig); i havent understood how to receive this signal from the calling thread. i would ideally like to pass some parameters (in this case, the char that was pressed from the thread polling for keyboard interrupts to the other).

how do i pass variables from one thread to another?

thanks in advance.

Sounds like you want to use condition variables (pthread_cond_t). Threads programming can be tricky, so you should pick up a good book on the subject. I personally prefer "Programming with POSIX Threads" by David R. Butenhof. It's very readable, and has a nice reference in the back.

thanks for the suggestion - will see if i can get it from sompleace.

If you want to read about threads..
there is a solaris pdf about posix threads..not proprietary...i ahve made it sure..
try looking for it .. if you want i can send it to you
another nice place to read about threads is:
good old stevens: UNIX Network Programming, Volume 1: Networking APIs - Sockets and XTI

some stuff is there in that books second volume ...IPC....

there are chapters dedicated to threads...
plus a must have/must read for any network programmer..
