How to prevent gdb to send Interrupt signals to child processes
Hi,
I have a program which invokes child processes and communicates with the processes. When I run the program under gdb and say interrupt, all the child processes are dying. Here I am not interested in debugging the child processes. But I don't want my child processes to be killed as my parent process dies as soon as the child process is killed. Also I have no access to the child process code for any modifications. My assumption is that gdb sends interrupt signals to child processes because of which they are dying (but I am not sure about this).
I have tried "handle sigint nopass" on gdb. But it did not work for me.Please let me know if there is any way to prevent gdb to send interrupt signals to child processes.
Thanks in advance,
klnarayana

Hello all, I am trying to create n child processes and control them from a parent process; say make child 3 print its pid and then child 5 do the same and some other stuff. Is there a way to accomplishing this after all the child processes are created via a call to fork().
Thank you,

runlim
RUNLIM(1) General Commands Manual RUNLIM(1)
NAME
runlim - a program to run benchmarks
SYNOPSIS
runlim [ options ...] command [ arguments ...]
DESCRIPTION
run is a tool that can be used to run and control benchmarks. It executes a given command with (optional) arguments, samples resource
usage during the run, and kills the process (and its child processes) if a certain time and/or space limit is exhausted.
Every 100 milliseconds, runlim takes a sample of the program's resource utilization, and logs status information to stderr every second.
Optionally, the status can be logged to a file.
Multi-threaded programs can be limited by setting a wall clock timeout. runlim follows the time accumulation scheme of GNU time for multi-
threaded programs and programs that spawn multiple child-processes: time spent in each thread/child is summed up, unless you are only
interested in walk clock time.
OPTIONS
runlim accepts the following options:
-h, --help
Show summary of options.
--version
Show version of program.
-o FILE, --output-file=FILE
Overwrite or create FILE for output logging.
-s NUM, --space-limit=NUM
Set space limit to NUM megabytes.
-t NUM, --time-limit=NUM
Set time limit to NUM seconds.
-r NUM, --real-time-limit=NUM
Set real time limit to NUM seconds.
-k, --kill
Propagate signals.
SEE ALSO
time(1), timelimit(1), timeout(1), time(7).
