shell script signal handler

AIX 4.3.3 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...

signal handler problems

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); } ...

Runaway SIGALRM signal handler

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...

Usage of exit() inside a signal handler

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...

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...

SIGCHLD interrupts its own handler

Hi. I have a program whose job it is to manage 15 child processes. Sometimes these children die (sometimes deliberately other times with a SEGV). This causes a SIGCHLD to be sent to my program which uses waitpid() in the signal handler to gather information and, in most cases, restart the child....

Perl Signal Handler

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. ...

DtTermSubprocReap(library call) 										   DtTermSubprocReap(library call)

NAME

       DtTermSubprocReap -- allow a DtTerm widget to clean up after subprocess termination

SYNOPSIS

       #include <Dt/Term.h>
       void DtTermSubprocReap(
       pid_t pid,
       int *stat_loc);

DESCRIPTION

       The DtTermSubprocReap function allows DtTerm widgets to function correctly in applications that have installed a SIGCHLD signal handler.

       The pid argument specifies the process ID of the child process wait(2) returns.

       The stat_loc argument specifies the termination information wait(2) returns.

RETURN VALUES

       The DtTermSubprocReap function returns no value.

APPLICATION USAGE

       The DtTermSubprocReap function allows an application to install its own SIGCHLD signal handler.

       The application must install its own SIGCHILD signal handler and call DtTermSubprocReap if the DtTerm widget was created with the DtSubpro-
       cessTerminatorCatch resource set to False.

       The application must call the DtTermSubprocReap function after performing a wait(2) (or associated function) on a terminated child process.
       If the child process is associated with a DtTerm widget, the widget's data structures are cleaned up and the associated callbacks invoked.

SEE ALSO

       Dt/Term.h - DtTerm(5), DtTerm(3), signal(5), wait(2).
