SDL_PushEvent(3) SDL API Reference SDL_PushEvent(3)NAME
SDL_PushEvent - Pushes an event onto the event queue
int SDL_PushEvent(SDL_Event *event);
The event queue can actually be used as a two way communication channel. Not only can events be read from the queue, but the user can also
push their own events onto it. event is a pointer to the event structure you wish to push onto the queue.
Pushing device input events onto the queue doesn't modify the state of the device within SDL.
Returns 0 on success or -1 if the event couldn't be pushed.

SDL_SetEventFilter(3) SDL API Reference SDL_SetEventFilter(3)NAME
SDL_SetEventFilter - Sets up a filter to process all events before they are posted to the event queue.
void SDL_SetEventFilter(SDL_EventFilter filter);
This function sets up a filter to process all events before they are posted to the event queue. This is a very powerful and flexible fea-
ture. The filter is prototyped as:
typedef int (*SDL_EventFilter)(const SDL_Event *event);
If the filter returns 1, then the event will be added to the internal queue. If it returns 0, then the event will be dropped from the
queue. This allows selective filtering of dynamically.
There is one caveat when dealing with the SDL_QUITEVENT event type. The event filter is only called when the window manager desires to
close the application window. If the event filter returns 1, then the window will be closed, otherwise the window will remain open if pos-
sible. If the quit event is generated by an interrupt signal, it will bypass the internal queue and be delivered to the application at the
next event poll.
Events pushed onto the queue with SDL_PushEvent or SDL_PeepEvents do not get passed through the event filter.
Be Careful! The event filter function may run in a different thread so be careful what you do within it.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
