See man sigaction, using a sa_sigaction callback instead of a sa_handler one means one of the arguments passed to the signal handler is a siginfo_t * containing a whole slew of items, one of which is the pid of the calling process.

#matrixmadhan & Corona688 all.
I got the above scenario working, and now i m able to get the child's pid in signal handler using sigaction siginfo structure. Still i m doing some optimization and improvement in my program. But thanks to all especially matrixmadhan & Corona688 who showed interest in my problem.

Corona688 - thanks , yes used the same structure of siginfo_t* to know the child pid, i was just going through sigaction tutorial and found that, but i m happy u gave same solution.

I will be back some new things.

Thank you all.

Shared memory for shared library

I am writing a shared library in Linux (but compatible with other UNIXes) and I want to allow multiple instances to share a piece of memory -- 1 byte is enough. What's the "best" way to do this? I want to optimize for speed and portability. Obviously, I'll have to worry about mutual exclusion. (0 Replies)
