N Sep 17 8791 Sam Lantinga Re: tks source released Date: Sun, 07 Sep 2003 02:51:58 +0200 From: Stephane Marchesin Subject: [SDL] Two little patches Compiling SDL with a recent gcc (gcc 3.3.1, 3.3 doesn't have this behaviour) gives some nasty warnings : SDL_blit_A.c: In function `BlitRGBtoRGBSurfaceAlpha128MMX': SDL_blit_A.c:223: warning: integer constant is too large for "long" type SDL_blit_A.c:225: warning: integer constant is too large for "long" type SDL_blit_A.c:227: warning: integer constant is too large for "long" type [...] The first attached patch (longlongfix.patch) tells gcc to really treat those constants as unsigned long long and not long. The second patch (nasinclude.patch) fixes an include problem I had while compiling nas audio : when the <audio/audiolib.h> file lies in /usr/X11R6/include, a -I/usr/X11R6/include option is needed or the file isn't found.

\fBSDL_Overlay *\fBSDL_CreateYUVOverlay\fP\fR(\fBint width, int height, Uint32 format, SDL_Surface *display\fR);
.SH "DESCRIPTION"
.PP
\fBSDL_CreateYUVOverlay\fP creates a YUV overlay of the specified \fBwidth\fR, \fBheight\fR and \fBformat\fR (see \fI\fBSDL_Overlay\fR\fR for a list of available formats), for the provided \fBdisplay\fR\&. A \fI\fBSDL_Overlay\fR\fR structure is returned\&.
.PP
The term \&'overlay\&' is a misnomer since, unless the overlay is created in hardware, the contents for the display surface underneath the area where the overlay is shown will be overwritten when the overlay is displayed\&.
