get_gfx_mode_type(3alleg4) Allegro manual get_gfx_mode_type(3alleg4) NAME
get_gfx_mode_type - Retrieves type information for a specific graphics card. Allegro game programming library. SYNOPSIS
#include <allegro.h> int get_gfx_mode_type(int graphics_card); DESCRIPTION
This function lets you determine the types of operating modes that a specific graphics card driver operates in. It will tell you whether it is a windowed, fullscreen, definitely windowed or fullscreen, and/or a magic driver. The value returned is a bitfield consisting of these fields: GFX_TYPE_UNKNOWN GFX_TYPE_WINDOWED GFX_TYPE_FULLSCREEN GFX_TYPE_DEFINITE GFX_TYPE_MAGIC The return value will only be equivalent to GFX_TYPE_UNKNOWN when it is a driver unrecognized on that platform, or it is a bogus value. Test for the other types by using a bitwise AND. If the driver is windowed or fullscreen, it will also have the definite flag set. For example, int gfx_type = get_gfx_mode_type(GFX_AUTODETECT_WINDOWED); gfx_type would have the GFX_TYPE_WINDOWED, GFX_TYPE_DEFINITE, and GFX_TYPE_MAGIC flags set. Allegro needs to be initialized first. Example: /* Accept the use of only windowed drivers in our selection dialog */ int accept_windowed(int card , int w , int h , int color_depth) { if (get_gfx_mode_type(card) & GFX_TYPE_WINDOWED) return 0; return 1; } /* In main: */ gfx_mode_select_filter(&card, &w, &h, &color_depth, accept_windowed); RETURN VALUE
Returns a bitfield describing the graphics mode type. SEE ALSO
