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.

#include "SDL_nxvideo.h"

extern WMcursor * NX_CreateWMCursor (_THIS, Uint8 * data, Uint8 * mask, int w, int h, int hot_x, int hot_y) ;
void NX_FreeWMCursor (_THIS, WMcursor * cursor) ;
extern void NX_WarpWMCursor (_THIS, Uint16 x, Uint16 y) ;
extern int NX_ShowWMCursor (_THIS, WMcursor * cursor) ;
