Date: Sun, 29 Feb 2004 15:14:22 +0200 From: Martin_Storsj Subject: Dynamic loading of ALSA I recently discovered that SDL can dynamically load ESD and aRts, and made a patch which adds this same functionality to ALSA. The update for configure.in isn't too good (it should e.g. look for libasound.so in other directories than /usr/lib), because I'm not too good at shellscripting and autoconf. The reason for using dlfcn.h and dlopen instead of SDL_LoadLibrary and SDL_LoadFunction is that libasound uses versioned symbols, and it is necessary to load the correct version using dlvsym. This isn't probably any real portability issue, because ALSA is linux-only.

.SH "NAME"
SDL_SetClipRect\- Sets the clipping rectangle for a surface\&.
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"
.sp
\fBvoid \fBSDL_SetClipRect\fP\fR(\fBSDL_Surface *surface, SDL_Rect *rect\fR);
.SH "DESCRIPTION"
.PP
Sets the clipping rectangle for a surface\&. When this surface is the destination of a blit, only the area within the clip rectangle will be drawn into\&.
.PP
The rectangle pointed to by \fBrect\fR will be clipped to the edges of the surface so that the clip rectangle for a surface can never fall outside the edges of the surface\&.
.PP
If \fBrect\fR is \fBNULL\fP the clipping rectangle will be set to the full size of the surface\&.
