Description
int
proc_close ( resource process)
proc_close() is similar to popen()
except that it only works on processes opened by
proc_open().
proc_close() waits for the process to terminate, and
returns it's exit code. If you have open pipes to that process, you
should fclose() them prior to calling this function in
order to avoid a deadlock - the child process may not be able to exit
while the pipes are open.
