Function SDL_SetSurfaceRLE 

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

Set the RLE acceleration hint for a surface.

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

Parameters

• surface: the SDL_Surface structure to optimize.
• enabled: true to enable RLE acceleration, false to disable it.

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.
