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 "DESCRIPTION"
.PP
The inverse of \fI\fBSDL_GetModState\fP\fR, \fBSDL_SetModState\fP allows you to impose modifier key states on your application\&.
.PP
Simply pass your desired modifier states into \fBmodstate\fR\&. This value my be a logical OR\&'d combination of the following:
