Hi,
when I execute a script on unix AIX, I've got an error message:
"Execution: 85328 Signal d'alarme".
If I edit this file with "vi", I ve got the same error after a while (about 1 minute).
If I try with another user I still have the problem.
But if I rename this file, no problem.

I am trying to write a signal to exit when a process times out. What I have come up with from poking around the web is this.

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)

I'm writing a function right now, and I want to set an alarm to avoid a timeout, here's the general idea of my code:

amt = read(fd, &t->buf, TASKBUFSIZ - tailpos); //do a read
when the alarm goes off, i want to check the value of "amt"

Our small company, about 5 users, need a basic script that scans mapped network drives (example: drive b,c,d, e, and f) for hard drive usage. This needs to send a report to myself in any type of basic notepad format (easy to read and decipher) for drives that have reached 80% usage... any ideas? ... (1 Reply)
Hi,
A basic sed question.
I have a set of files. In each file there is a number that I want replaced. For example, if I run sed I should get the following:
% cat test2.txt
#goofy//171.00
goofy 171.00
% sed -i 's/171/xxx/g' test2.txt
% cat test2.txt
#goofy//xxx.00
goofy xxx.00

SIGSUSPEND(2) Linux Programmer's Manual SIGSUSPEND(2)NAME
sigsuspend - wait for a signal
SYNOPSIS
#include <signal.h>
int sigsuspend(const sigset_t *mask);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
sigsuspend(): _POSIX_C_SOURCE >= 1 || _XOPEN_SOURCE || _POSIX_SOURCE
DESCRIPTION
sigsuspend() temporarily replaces the signal mask of the calling process with the mask given by mask and then suspends the process until
delivery of a signal whose action is to invoke a signal handler or to terminate a process.
If the signal terminates the process, then sigsuspend() does not return. If the signal is caught, then sigsuspend() returns after the sig-
nal handler returns, and the signal mask is restored to the state before the call to sigsuspend().
It is not possible to block SIGKILL or SIGSTOP; specifying these signals in mask, has no effect on the process's signal mask.
RETURN VALUE
sigsuspend() always returns -1, with errno set to inndicate the error (normally, EINTR).
ERRORS
EFAULT mask points to memory which is not a valid part of the process address space.
EINTR The call was interrupted by a signal.
CONFORMING TO
POSIX.1-2001.
NOTES
Normally, sigsuspend() is used in conjunction with sigprocmask(2) in order to prevent delivery of a signal during the execution of a criti-
cal code section. The caller first blocks the signals with sigprocmask(2). When the critical code has completed, the caller then waits
for the signals by calling sigsuspend() with the signal mask that was returned by sigprocmask(2) (in the oldset argument).
See sigsetops(3) for details on manipulating signal sets.
