RE: Cannot capture SIGPIPE

["Parvez Pathan" <parvezp@lycos.com>]

Hi,
 Thanks for the reply. One question that has now started lingering my mind is that Is it correct to pass the kill signal to the process as kill  will always try to terminate the process, whereas I do not want to terminate the process.
  Secondly, I did have some luck. Ater every write I check for 2 conditions, the return val after write and is errno is set to EPIPE. But still my handler does not get called. Strange!!

Thanks 
Parvez

>Hi All,
>  I have  a server program which connect to clients c1 and c2. The server reads from c1 and writes to c2. Whenever c2 dies(or is killed) I get a SIGPIPE at the server. I have tried to capture the SIGPIPE but cant trap it. Some part of my code is as follows:

>void cleanup (int x) { printf ("Quitting..."); exit(0); }
>void back_to_work (int x) { printf ("Not Quitting..."); return; }

>main ()
