shell script signal handler

signal handler for SIGCHLD

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...

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...

Problem with signal handler and interrupted system call

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...

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. ...

raise

RAISE(3)						     Linux Programmer's Manual							  RAISE(3)

NAME

       raise - send a signal to the caller

SYNOPSIS

       #include <signal.h>

       int raise(int sig);

DESCRIPTION

       The raise() function sends a signal to the calling process or thread.  In a single-threaded program it is equivalent to

	   kill(getpid(), sig);

       In a multithreaded program it is equivalent to

	   pthread_kill(pthread_self(), sig);

       If the signal causes a handler to be called, raise() will return only after the signal handler has returned.

RETURN VALUE

       raise() returns 0 on success, and nonzero for failure.

CONFORMING TO

       C89, C99, POSIX.1-2001.

NOTES

       Since  version  2.3.3, glibc implements raise() by calling tgkill(2), if the kernel supports that system call.  Older glibc versions imple-
       mented raise() using kill(2).

SEE ALSO

       getpid(2), kill(2), sigaction(2), signal(2), pthread_kill(3), signal(7)

COLOPHON

       This page is part of release 3.53 of the Linux man-pages project.  A description of the project, and information about reporting bugs,  can
