system(3) does a fork and exec, to put it simply. You might want to look at popen(3), which returns a FILE pointer that allows you to read output from or write input to the command that you're executing.

Edit: Aaaand I just noticed that pludi has suggested exactly the same thing.

ascommand

ASCOMMAND(1x)															     ASCOMMAND(1x)

NAME

       ascommand - send commands to AfterStep

SYNOPSIS

       ascommand [-f file] [-h] [-i] [-v] [-w id] [--] [command]

DESCRIPTION

       This  manual  page  documents briefly the ascommand command.  This manual page was written for the Debian distribution because the original
       program does not have a manual page.

       ascommand is a program, which sends commands to the AfterStep Window Manager.

OPTIONS

       -f --file
	      input commands from file (- means stdin)

       -h --help
	      this help

       -i --interactive starts interactive communication with AfterStep

       -v --version
	      print version information

       -w --window-id
	      window id to send to AfterStep (in hex)

       --     end parsing of command line options

       command
	      command to send to AfterStep

       If -f - or -i is specified, ascommand will read commands from standard input, and print results on standard output.  -i is noisier than	-f
       -.
