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

\fBcolors\fR
Pointer to \fI\fBSDL_Color\fR\fR structures that make up the palette\&.
.SH "DESCRIPTION"
.PP
Each pixel in an 8-bit surface is an index into the \fBcolors\fR field of the \fBSDL_Palette\fR structure store in \fI\fBSDL_PixelFormat\fR\fR\&. A \fBSDL_Palette\fR should never need to be created manually\&. It is automatically created when SDL allocates a \fBSDL_PixelFormat\fR for a surface\&. The colors values of a \fI\fBSDL_Surface\fR\fRs palette can be set with the \fI\fBSDL_SetColors\fP\fR\&.
