SIGINT handler with Fork()

xface66 · 04-02-2007, 11:37 AM

hi everyone,

i have a program that forks-off a child process. I want to override SIGINT handler. Means when user breaks the program with ctrl+c my handler will run.
I have done it but my handler runs twice one for parent, one for child process i think.
What must i do to prevent this? I want to deallocate memory and exit the child and parent processes.
Do u have any solutions?

Thanks in advance.

Code:

The  child  process  inherits  the
     following attributes from the parent process:
o  signal handling settings (that is,  SIG_DFL,  SIG_IGN,
           SIG_HOLD, function address)

and in the child for the signal handler set the default function to SIG_IGN
