Function fermium::surface::SDL_SetSurfaceRLE

pub unsafe extern "C" fn SDL_SetSurfaceRLE(
    surface: *mut SDL_Surface, 
    flag: c_int
) -> c_int

Sets the RLE acceleration hint for a surface.

If RLE is enabled, colorkey and alpha blending blits are much faster, but the surface must be locked before directly accessing the pixels.

Return: 0 on success, or -1 if the surface is not valid
