Subject: [SDL] Detecting Opteron CPU features
I can now get SDL_cpuinfo.c to detect the AMD Opteron's RDTSC, MMX, MMXEXT,
3DNOW, 3DNOWEXT, SSE, and SSE2 instruction set extensions under Linux. It
took one #ifdef'ed block of new asm code to account for the 64-bit flags
register, but the other two blocks worked fine without modification, just
needed to modify the #ifdef's a bit.

.TH "SDL_ListModes" "3" "Tue 11 Sep 2001, 23:01" "SDL" "SDL API Reference" .SH "NAME" SDL_ListModes\- Returns a pointer to an array of available screen dimensions for the given format and video flags .SH "SYNOPSIS" .PP \fB#include "SDL\&.h" .sp \fBSDL_Rect **\fBSDL_ListModes\fP\fR(\fBSDL_PixelFormat *format, Uint32 flags\fR); .SH "DESCRIPTION" .PP Return a pointer to an array of available screen dimensions for the given format and video flags, sorted largest to smallest\&. Returns \fBNULL\fP if there are no dimensions available for a particular format, or \fB-1\fR if any dimension is okay for the given format\&. .PP If \fBformat\fR is \fBNULL\fP, the mode list will be for the format returned by \fISDL_GetVideoInfo()\fR->\fBvfmt\fR\&. The \fBflag\fR parameter is an OR\&'d combination of \fIsurface\fR flags\&. The flags are the same as those used \fI\fBSDL_SetVideoMode\fP\fR and they play a strong role in deciding what modes are valid\&. For instance, if you pass \fBSDL_HWSURFACE\fP as a flag only modes that support hardware video surfaces will be returned\&. .SH "EXAMPLE" .PP .nf \f(CWSDL_Rect **modes; int i; \&. \&. \&. /* Get available fullscreen/hardware modes */ modes=SDL_ListModes(NULL, SDL_FULLSCREEN|SDL_HWSURFACE); /* Check is there are any modes available */ if(modes == (SDL_Rect **)0){ printf("No modes available! "); exit(-1); } /* Check if or resolution is restricted */ if(modes == (SDL_Rect **)-1){ printf("All resolutions available\&. "); } else{ /* Print valid modes */ printf("Available Modes "); for(i=0;modes[i];++i) printf(" %d x %d ", modes[i]->w, modes[i]->h); } \&. \&.\fR .fi .PP .SH "SEE ALSO" .PP \fI\fBSDL_SetVideoMode\fP\fR, \fI\fBSDL_GetVideoInfo\fP\fR, \fI\fBSDL_Rect\fR\fR, \fI\fBSDL_PixelFormat\fR\fR ...\" created by instant / docbook-to-man, Tue 11 Sep 2001, 23:01
