Macro Definition Documentation

#define retroflat_bitmap_has_flags	(		bmp,
			f )

Value:

(NULL != (bmp) && (f) == ((f) & (bmp)->tex.flags))

#define retroflat_is_waiting_for_frame ( )

Value:

(RETROFLAT_FLAGS_WAIT_FOR_FPS == \

(g_retroflat_state->retroflat_flags & RETROFLAT_FLAGS_WAIT_FOR_FPS))
