Thoren <pthoren@cs.uml.edu> Reply-To: "sdl@libsdl.org" <sdl@libsdl.org> To: "sdl@libsdl.org" <sdl@libsdl.org> Subject: [SDL] BUG in src/video/windx5/SDL_dx5events.c I tracked down a bug that crashed my program on Windows *all* the time. FILE: src/video/windx5/SDL_dx5events.c FUNCTION: handle_mouse BUG: SDL_PublicSurface is being dereferenced when it is NULL. I added the following to the very begining of handle_mouse and it solved my crashing problems: if (SDL_PublicSurface == NULL) return; ~ Philip D.S. Thoren

.SH "NAME"
SDL_PumpEvents\- Pumps the event loop, gathering events from the input devices\&.
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"
.sp
\fBvoid \fBSDL_PumpEvents\fP\fR(\fBvoid\fR);
.SH "DESCRIPTION"
.PP
Pumps the event loop, gathering events from the input devices\&.
.PP
\fBSDL_PumpEvents\fP gathers all the pending input information from devices and places it on the event queue\&. Without calls to \fBSDL_PumpEvents\fP no events would ever be placed on the queue\&. Often calls the need for \fBSDL_PumpEvents\fP is hidden from the user since \fI\fBSDL_PollEvent\fP\fR and \fI\fBSDL_WaitEvent\fP\fR implicitly call \fBSDL_PumpEvents\fP\&. However, if you are not polling or waiting for events (e\&.g\&. your filtering them), then you must call \fBSDL_PumpEvents\fP to force an event queue update\&.
.PP
.RS
\fBNote:  
.PP
You can only call this function in the thread that set the video mode\&.
