Instead of using defined error numbers, the coder decided to use a signal number as the return code from the perl code. SIGINT (EINTR) == 2 on most systems.

I am trying to write a signal handler into a ksh shell script. I would like to capture the SIGTERM, SIGINT, and the SIGTSTP signals, print out a message to the terminal, and continue executing the script. I have found a way to block the signals:
#! /bin/ksh
SIGTERM=15
SIGINT=2... (2 Replies)
Hi,
I have an c++ application which uses the function fork and execvp().
The parent does not wait until the child ends. The parents just creates children and let them do their stuff.
You can see the parent program as a batch-manager.
I have added a SIGCHLD handler to the program:
void... (3 Replies)
Hey guys,

I wrote this signal handler: void handle_sigint()
{
write(2,"handling sigint\n",16);
write(1,"\nshell% ",8);
}

I have written a program to demonstrate a problem I have encountered when using BSD style asynchronous input using the O_ASYNC flag in conjunction with a real time interval timer sending regular SIGALRM signals to the program. The SIGIO handler obeys all safe practices, using only an atomic update... (8 Replies)

I catch SIGUSR1 in a signal handler and I try to close a file and then exit. The result is inconsistent. Sometimes the process exit and sometimes it returns to the original state before the signal handler was invoked.
Perhaps exit is not legal in... (8 Replies)

The problem is that I want my main while loop to wait until the next full second begins, to... (2 Replies)
I have a problem with signal handlers not working.
I have a long 1000 line code and somehow this code for signal handling is not working:
$SIG{INT} = \&interrupt;
sub interrupt {
print STDERR "Caught a control c!\n";
exit; # or just about anything else you'd want to do
}
Any... (2 Replies)
