Function SDL_FillSurfaceRect 

pub unsafe extern "C" fn SDL_FillSurfaceRect(
    dst: *mut SDL_Surface,
    rect: *const SDL_Rect,
    color: Uint32,
) -> bool

Perform a fast fill of a rectangle with a specific color.

color should be a pixel of the format used by the surface, and can be generated by SDL_MapRGB() or SDL_MapRGBA(). If the color value contains an alpha component then the destination is simply filled with that alpha information, no blending takes place.

If there is a clip rectangle set on the destination (set via SDL_SetSurfaceClipRect()), then this function will fill based on the intersection of the clip rectangle and rect.

Parameters

• dst: the SDL_Surface structure that is the drawing target.
• rect: the SDL_Rect structure representing the rectangle to fill, or NULL to fill the entire surface.
• color: the color to fill with.

Return value

Returns true on success or false on failure; call SDL_GetError() for more information.

Thread safety

This function can be called on different threads with different surfaces.

Availability

This function is available since SDL 3.2.0.
