See the thread "Communication between threads of same PIDs" in this

thanks for the response,
It does not solve the problem.

In the pthread_library clone call is used , In the man page of clone
its given that
if CLONE_SIGHAND is not defined, the signal handlers will not be shared
between threads.
I recompiled the pthread library with out CLONE_SIGHAND .

I linked the program with the new library , It has been ok in the
do_fork call in the pthread funciton, A new struct of task_struct->sig
is allocated. Also i have seen that the sigaction function call in the
thread modifies and install a new handler in this already allocated
task_struct->sig structure.
Inspite of all this the last sig handler function is getting called
when i send the signal to the first thread. Any clue???

thanks
