NAME
A static function of omni::application::shutdown_handler
omni::application::shutdown_handler::detach
A static function of omni::application::shutdown_handler
#include <omni/application.hpp>void omni::application::shutdown_handler::detach(const omni::callback& shutdown_func)
DESCRIPTION
Detaches an
Calling this function after an
top
Detaches an
omni::callback that was first attached via the omni::application::shutdown_handler::attach function. If the callback was never first attached, this function has no effect.Calling this function after an
omni::application::run context has returned will have no effect since the run function will have already returned thus calling the delegates.

CONSIDERATIONS
This function will only have an effect if you have explicitly called one of the
