killproc [-p pidfile] pathname [signal]
This stops the specified program. The program is
found using the algorithm given above. If a
signal is specified, using the
-signal_name or -signal_number syntaxes
as specified by the kill command,
the program is sent that signal.
Otherwise, a SIGTERM followed by a SIGKILL
after some number of seconds shall be sent.
If a program has been terminated, the pidfile should be removed if the
terminated process has not already done so.
Compliant applications may use the basename instead of the
pathname.
killproc should return the LSB defined exit status codes. If called
without a signal, it shall return 0 if the program has been stopped or
is not running and not 0 otherwise. If a signal is given, it shall return 0
only if the program is running.
