annotate docs/man3/SDL_ListModes.3 @ 3950:9d9e15ab1697 SDL-1.2
Check if yasm supports a nasm-specific syntax we use (it doesn't in 0.5.0,
which is still common in Linux distros, and does in 0.6.0). Disable it if we
don't, attempting to fallback to using nasm. Thanks to Mike Frysinger for the
patch.
Fixes Bugzilla #393.

| 3 SDL_ListModes\- Returns a pointer to an array of available screen dimensions for the given format and video flags | |
| 4 .SH "SYNOPSIS" | |

| 7 .sp | |
| 8 \fBSDL_Rect **\fBSDL_ListModes\fP\fR(\fBSDL_PixelFormat *format, Uint32 flags\fR); | |
| 9 .SH "DESCRIPTION" | |
| 10 .PP | |
| 11 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\&. | |
| 12 .PP | |
| 13 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\&. | |
