SDL_BlitSurfaceUnchecked

Perform low-level surface blitting only.

Header File

Defined in <SDL3/SDL_surface.h>

Syntax

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

Function Parameters

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

Return Value

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

Remarks

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

Thread Safety

The same destination surface should not be used from two threads at once. It is safe to use the same source surface from multiple threads.

Version

This function is available since SDL 3.1.3.
