Hi,
I have a main loop which calls a sub loop, which finally returns to the main loop itself. The main loop runs when a flag is set. Now, I have a signal handler for SIGINT, which resets the flag and thus stops the main loop. Suppose I send SIGINT while the program is in subloop, I get an error... (1 Reply)

Hello,
i am using the sigaction function to handle the SIGCHLD signal.Is it possible to use a class member function as the handler function (the sa_handler member of the sigaction structure)?
The function's signature is:
void (*sa_handler)(int);so i don't think i can use a static member function... (2 Replies)

I want to execute awk command without quotes.

above code should be something like:

mod-active
MOD-ACTIVE(8) InterNetNews Documentation MOD-ACTIVE(8)NAME
mod-active - Batch processing of newsgroups creation and removal commands
SYNOPSIS
mod-active [ctlinnd-command-file ...]
DESCRIPTION
mod-active is a Perl script that updates the active file based on its input lines of ctlinnd "newgroup", "rmgroup" and "changegroup"
commands. It pauses the server briefly while the existing active file is read and rewritten, which not only keeps innd from updating the
active file but also locks against other instances of mod-active.
The script must be run as the news user.
The input to mod-active can come either from one or more ctlinnd-command-file files named on the command line, or from the standard input.
Typically its input is the output from the docheckgroups or actsync commands. Every line which contains the string "ctlinnd newgroup",
"ctlinnd rmgroup", or "ctlinnd changegroup", optionally preceded by whitespace and/or the path to ctlinnd, is noted for the update.
Redundant commands, such as a newgroup directive for a group that already exists, are silently ignored. All other lines in the input are
also silently ignored. After the new active file has been generated, the existing one is renamed to active.old and the new one is moved
into place. The script then displays the differences between the two files. Any groups that were added to the active file are also added
to the active.times file with the string "checkgroups-update".
Please note that no syntax checking is performed on group names by mod-active.
BUGS
Though innd is paused while mod-active works, it is not inconceivable that there could be a conflict if something else tries to update the
active file during the relatively short time that mod-active is working. The two most realistic ways for this to happen are either by an
administrator concurrently doing a manual ctlinnd command, or by innd receiving a control message, then mod-active pausing the server, then
the control message handler script that innd forked running its own ctlinnd command while mod-active is working. Note that such scenarios
are very unlikely to happen.
