Determine whether a floating point rectangle has no area.
Defined in SDL_rect.h, but apps should use #include <SDL3/SDL.h>
const SDL_FRect *r); SDL_FORCE_INLINE SDL_bool SDL_RectEmptyFloat(
r | the rectangle to test. |
Returns SDL_TRUE if the rectangle is "empty", SDL_FALSE otherwise.
A rectangle is considered "empty" for this function if r
is NULL, or if r
's width and/or height are <= 0.0f.
Note that this is a forced-inline function in a header, and not a public API function available in the SDL library (which is to say, the code is embedded in the calling program and the linker and dynamic loader will not be able to find this function inside SDL itself).
It is safe to call this function from any thread.
This function is available since SDL 3.0.0.
