Date: Mon, 5 May 2003 00:08:51 -0400 From: Darrell Walisser Subject: SDL Active Events Patch Hi Guys, I was reading sdl-devel the other day and remembered we don't handle SDL_APPACTIVE and SDL_APPMOUSEFOCUS. I hacked together a quick patch to do just this. One thing to note - there are actually two ways to "iconify" the SDL window (which sets SDL_APPACTIVE): hiding the entire application (for example, option-click on some other window) and minimizing the window to the dock. I treat both as SDL_APPACTIVE, since the window is no longer visible. Cheers, Darrell

11 This function takes two audio buffers of \fBlen\fR bytes each of the playing audio format and mixes them, performing addition, volume adjustment, and overflow clipping\&. The \fBvolume\fR ranges from 0 to \fBSDL_MIX_MAXVOLUME\fP and should be set to the maximum value for full audio volume\&. Note this does not change hardware volume\&. This is provided for convenience -- you can mix your own audio data\&.

16 Do not use this function for mixing together more than two streams of sample data\&. The output from repeated application of this function may be distorted by clipping, because there is no accumulator with greater range than the input (not to mention this being an inefficient way of doing it)\&. Use mixing functions from SDL_mixer, OpenAL, or write your own mixer instead\&.
