NAME
A static function of omni::application::signal_handler
omni::application::signal_handler::detach
A static function of omni::application::signal_handler
#include <omni/application.hpp>
void omni::application::signal_handler::detach(const omni::application::signal_handler::callback& sig_func)
DESCRIPTION
Detaching a specific delegate will stop that function from receiving system signal events. Detaching a delegate that has not been initially attached has no effect.
