-.SH "NAME"
-SDL_SetEventFilter \- Sets up a filter to process all events before they are posted to the event queue\&.

-.PP
-\fB#include "SDL\&.h"

-.SH "DESCRIPTION"
-.PP
-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 feature\&. The filter is prototyped as:
-.PP
-.nf
-\f(CWtypedef int (*SDL_EventFilter)(const SDL_Event *event);\fR
-.fi
-.PP
- If the filter returns \fB1\fR, then the event will be added to the internal queue\&. If it returns \fB0\fR, then the event will be dropped from the queue\&. This allows selective filtering of dynamically\&.
-.PP
-There is one caveat when dealing with the \fBSDL_QUITEVENT\fP 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 possible\&. 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\&.

-\fBNote:
-.PP
-Events pushed onto the queue with \fI\fBSDL_PushEvent\fP\fR or \fI\fBSDL_PeepEvents\fP\fR do not get passed through the event filter\&.

-\fIBe Careful!\fP The event filter function may run in a different thread so be careful what you do within it\&.
