Fixed bug #750 Since many different event structures include windowID it should be placed near the beginning of the structure (preferably right after type) so it's position is the same between different events. This is to avoid code like this: if (event.type == SDL_WINDOWEVENT) win = event.window.windowID; else if ((SDL_EVENTMASK(event.type) & SDL_KEYEVENTMASK) != 0) win = event.key.windowID; else if (event.type == SDL_TEXTINPUT) win = event.text.windowID; else if (event.type == SDL_MOUSEMOTION) win = event.motion.windowID; else if ((SDL_EVENTMASK(event.type) & (SDL_MOUBUTTONDOWNMASK | SDL_MOUBUTTONUPMASK)) != 0) win = event.button.windowID; else if (event.type == SDL_MOUSEWHEEL) win = event.wheel.windowID; ... in favor of: win = event.window.windowID;

.SH "DESCRIPTION"
.PP
\fBSDL_CDPlayTracks\fP plays the given CD starting at track \fBstart_track\fR, for \fBntracks\fR tracks\&. 
.PP
\fBstart_frame\fR is the frame offset, from the beginning of the \fBstart_track\fR, at which to start\&. \fBnframes\fR is the frame offset, from the beginning of the last track (\fBstart_track\fR+\fBntracks\fR), at which to end playing\&.
.PP
\fBSDL_CDPlayTracks\fP should only be called after calling \fI\fBSDL_CDStatus\fP\fR to get track information about the CD\&.

\fBNote:  
.PP
Data tracks are ignored\&.

.SH "RETURN VALUE"
.PP
Returns \fB0\fR, or \fB-1\fR if there was an error\&.
