Subject: Fusionsound audio driver
attached is a diff containing a audio driver for the FusionSound
library. This sound library is closely related to DirectFB and uses the
same transport (fusion) as DirectFB when running applications "remote",
i.e. over the network. As such, it natively redirects sound where
DirectFB redirects video. This may be handy for everyone using SDL over
DirectFB.

3 SDL_GL_GetProcAddress \- Get the address of a GL function |

10 .PP | |
11 Returns the address of the GL function \fBproc\fR, or \fBNULL\fR if the function is not found\&. If the GL library is loaded at runtime, with \fI\fBSDL_GL_LoadLibrary\fP\fR, then \fIall\fP GL functions must be retrieved this way\&. Usually this is used to retrieve function pointers to OpenGL extensions\&. | |
