Date: Thu, 05 Feb 2009 18:07:35 +0100 From: Stefan Klug Subject: [SDL] SDL 1.3 WinCE backend as promised, I've started to work on the WinCE backend of SDL 1.3 I've modified the win32 video backend and the gdi renderer, to work properly in WinCE. The results till now are great, but there is still some work to do. Attached are two patches with my changes. I would be happy if someone could review and propably commit them. The first one (configure.in.patch) should be straight forward without any side effects. The second one does the necessary changes to the win32 backend. I was really unhappy to start slicing this shiny new backend with #ifdef/#endif but I saw no other option. The most problematic issues are: - WinCe has no GetDIBits, so its practically impossible to fill a BITMAPINFO with correct values. I therefore removed the bmi member from the GDI_RenderData in SDL_gdirender.c to prevent usage of a not or not properly initialized bmi. - In SDL_win32window.c I exchanged some ASCII function by their general counterparts, (In CE only the Unicode versions are available). I don't know if this has a negative effect when running in win32 Cheers Stefan

SDL_CDOpen \- Opens a CD-ROM drive for access\&.
.SH "SYNOPSIS"
.PP

\fBSDL_CD *\fBSDL_CDOpen\fP\fR(\fBint drive\fR);
.SH "DESCRIPTION"
.PP
Opens a CD-ROM drive for access\&. It returns a \fI\fBSDL_CD\fR\fR structure on success, or \fBNULL\fP if the drive was invalid or busy\&. This newly opened CD-ROM becomes the default CD used when other CD functions are passed a \fBNULL\fP CD-ROM handle\&. 
.PP
Drives are numbered starting with 0\&. Drive 0 is the system default CD-ROM\&.
