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:

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:

Hey guys,
I am trying to write a little shell, and was writing a signal handler to handle SIGINT (I am using 'stty intr ^C' and using ctrl-C to give SIGINT).
I wrote this signal handler: void handle_sigint()
{
write(2,"handling sigint\n",16);
write(1,"\nshell% ",8);
}

Is it ok to use exit() inside a signal handler?
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)
Hi,
I have a daq program that runs in an infinite loop until it receives SIGINT. A handler catches the signal and sets a flag to stop the while loop. After the loop some things have to be cleaned up.
The problem is that I want my main while loop to wait until the next full second begins, to... (2 Replies)

sub interrupt {

exit; # or just about anything else you'd want to do
}

I was working on some Perl code that does signal handling and I came across this one liner and wasn't sure what it was doing.
local $SIG{__DIE__} = sub {$! = 2; die $_;};
I think the first part of the anonymous subroutine is setting $! to 2, but I am not sure what the second part is doing. ... (1 Reply)

voice_set_playmode
voice_set_playmode(3alleg4) Allegro manual voice_set_playmode(3alleg4)NAME
voice_set_playmode - Adjusts the loop status of the specified voice. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
void voice_set_playmode(int voice, int playmode);
DESCRIPTION
Adjusts the loop status of the specified voice. This can be done while the voice is playing, so you can start a sample in looped mode (hav-
ing set the loop start and end positions to the appropriate values), and then clear the loop flag when you want to end the sound, which
will cause it to continue past the loop end, play the subsequent part of the sample, and finish in the normal way. The mode parameter is a
bitfield containing the following values:
PLAYMODE_PLAY
Plays the sample a single time. This is the default if you don't set the loop flag.
PLAYMODE_LOOP
Loops repeatedly through the sample, jumping back to the loop start position upon reaching the loop end.
PLAYMODE_FORWARD
Plays the sample from beginning to end. This is the default if you don't set the backward flag.
PLAYMODE_BACKWARD
Reverses the direction of the sample. If you combine this with the loop flag, the sample jumps to the loop end position upon reaching the
loop start (ie. you do not need to reverse the loop start and end values when you play the sample in reverse).
PLAYMODE_BIDIR
When used in combination with the loop flag, causes the sample to change direction each time it reaches one of the loop points, so it
alternates between playing forwards and in reverse.
