Willy Tarreau	d0807c3c60	[MEDIUM] signals: support redistribution of signal zero when stopping ... Signal zero is never delivered by the system. However having a signal to which functions and tasks can subscribe to be notified of a stopping event is useful. So this patch does two things : 1) allow signal zero to be delivered from any function of signal handler 2) make soft_stop() deliver this signal so that tasks can be notified of a stopping condition.	2010-08-27 18:26:11 +02:00
Willy Tarreau	24f4efa670	[MEDIUM] signals: add support for registering functions and tasks ... The two new functions below make it possible to register any number of functions or tasks to a system signal. They will be called in the registration order when the signal is received. struct sig_handler *signal_register_fct(int sig, void (*fct)(struct sig_handler *), int arg); struct sig_handler *signal_register_task(int sig, struct task *task, int reason);	2010-08-27 18:00:40 +02:00
Willy Tarreau	8f38bd0497	[MINOR] add basic signal handling functions ... These functions will be used to deliver asynchronous signals in order to make the signal handling functions more robust. The goal is to keep the same interface to signal handlers.	2009-05-10 09:24:23 +02:00
