#include "SDL3/SDL.h"

bool SDL_BlitSurfaceUnchecked(SDL_Surface *src, const SDL_Rect *srcrect, SDL_Surface *dst, const SDL_Rect *dstrect);

This is a semi-private blit function and it performs low-level surface blitting, assuming the input rectangles have already been clipped.

src: the SDL_Surface
structure to be copied from.
srcrect: the SDL_Rect
structure representing the rectangle to be copied, may not be NULL.
dst: the SDL_Surface
structure that is the blit target.
dstrect: the SDL_Rect
structure representing the target rectangle in the destination surface, may not be NULL.

Returns true on success or false on failure; call

SDL_GetError () for more information.

Only one thread should be using the src and dst surfaces at any given time.

This function is available since SDL 3.2.0.
