process semaphores cleanup problem

Hi all,

My is probem is that I want to do some cleanup action if a process gets ki
lled. Is there any way I can attach a cleanup routine ( like pthread_cleanup
_push: in case of pthreads) in a process (not a thread)


Actually My process deals with shared memory & semaphores...& if it gets ki
lled while semaphore is in locked state...there occurs a problem...(others p
rocessess can no longer use that shared memory resource)
So I want to install a Cleanup Handler ( in C language on linux platform) so
as to unlock the semaphores just prior to termination.


Help me guys........... :(

Look into signal handlers.
Then trap on say SIG_QUIT

You won't be able to trap SIG_KILL
