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.

voiddaemon_signal_done(void) Free resources of signal handling, should be called before daemon exit. Examplestestd.c. intdaemon_signal_fd(void) 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 The file descriptor or negative on failure Examplestestd.c. intdaemon_signal_init(ints,...) Installs signal handlers for the specified signals. Parameterss,... The signals to install handlers for. The list should be terminated by 0 Returns zero on success, nonzero on failure Examplestestd.c. intdaemon_signal_install(ints) Install a signal handler for the specified signal. Parameterss The signalto install handler for Returns zero onsuccess,nonzero on failure intdaemon_signal_next(void) Return the next signal received. This function will not block. Instead it returns 0 if no signal is queued. Returns The next queued signal if one is queued, zero if none is queued, negative on failure. Examplestestd.c.
