dsignal.h - Contains the API for serializing signals to a pipe for usage with select() or poll().
int daemon_signal_init (int s,...)
Installs signal handlers for the specified signals. int
daemon_signal_install (int s)
Install a signal handler for the specified signal. void
daemon_signal_done (void)
Free resources of signal handling, should be called before daemon exit. int
daemon_signal_next (void)
Return the next signal received. int daemon_signal_fd (void)
Return the file descriptor the daemon should select() on for reading.
Contains the API for serializing signals to a pipe for usage with select() or poll().
You should register all signals you wish to handle with select() in your main loop with daemon_signal_init() or daemon_signal_install(). After that you should sleep on the file descriptor returned by daemon_signal_fd() and get the next signal received with daemon_signal_next(). You should call daemon_signal_done() before exiting.
Definition in file dsignal.h.
Free resources of signal handling, should be called before daemon exit.
Examples
testd.c.
Return the file descriptor the daemon should select() on for reading. Whenever the descriptor is ready you should call daemon_signal_next() to get the next signal queued.
Returns
Examples
testd.c.
Installs signal handlers for the specified signals.
