Date: Sun, 25 Jul 2004 23:10:03 +0800 From: Chris Taylor Subject: SDL for Macintosh Programmer's Workshop: removed dynamic loading I'm working on a game called D2X which uses SDL, and I recently ported it to Mac OS 9. I used MPW to build it. It uses OpenGL. To get it to work, I had to build SDL so it doesn't dynamically load OpenGL. This is because I don't think MPW supports dynamic loading. The following patch makes sure when SDL is built under MPW, dynamic loading of shared libraries is disabled.

Gets a snapshot of the current keyboard state\&. The current state is return as a pointer to an array, the size of this array is stored in \fBnumkeys\fR\&. The array is indexed by the \fI\fBSDLK_*\fP\fR symbols\&. A value of 1 means the key is pressed and a value of 0 means its not\&. The pointer returned is a pointer to an internal SDL array and should not be freed by the caller\&.
