A C program contains several signal statements to remove a
lock file if the program gets killed:
/*Set up interrupt handler to catch ctrl-C so that lock file can be removed.*/
signal(SIGINT,crash);
signal(SIGBUS,crash);
signal(SIGSEGV,crash);
This part works. Those signals cause the "crash.c" module to
run and get rid of the lock. Is there a standard way to also print

Hi
I'm not sure if this is correct ...place to post but here goes
This is what i'm trying to do, I want to write a signal / alarm handler
( I don't know which hence the posting here, as once I know the proper
name /useage then I'll use google to try and find out more
information )....
Thus any tips or pointers would be helpful (and I'm using a UNIX variant as
OS)

Hi everyone,
I'd like to know when and how signals are used (e.g. SIGFPE, SIGABRT,
SIGTERM, SIGSEGV, SIGINT)? Thank you so much.

Hi,
I want to write a program, where until we give the value of j as
non zero, it should go on asking us values of i and j, displaying the
message "Division by zero: Floating point exception" for every input
of j as zero. Once we give the value of both i and j as non-zero, it
displays i/j and terminates.
This is the sample code i tried:
#include <signal.h>
void sig_s(int signo);

Hello,
1.
The prototype of function signal in signal.h:
void (*signal(int sig, void (*func)(int)))(int);
is some complex to me. Would you please explain it to me in detail with
the C language syntax itself. Thank you!

Hi,
Are Signal Handling part of ANSI C?
I am not able to find any reference of Sig Handling in Stephen Prata's
"C Primer Plus".
The usage of signals is to trap errors I guess. (It looks similiar to
the concept of try-catch to me.) It seems to relate more to nix OS. Are
signals handling part of Windows too?

Hi all
Iam having trouble with signal handler. Where will the execution
return after invoking a signal handler when that particular signal is
recieved? will return to the point where we register the signal?
The following code is recieveing recursive signals.
2 #include <stdio.h>
3 #include <stdlib.h>
4 #include <unistd.h>

I'm developing a program that runs using an asyncore loop. Right now
I can adequately terminate it using Control-C, but as things get
refined I need a better way to stop it. I've developed another
program that executes it as a child process using popen2.Popen4(). I
was attempting to use signals to stop it (using os.kill()) but I keep
running into a problem where sending the signal causes an infinite
loop of printing the message...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
