SDL_BlitSurfaceUnchecked

Perform low-level surface blitting only.

Header File

Defined in <SDL3/SDL_surface.h>

Syntax

int 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, or NULL to copy the entire surface.
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.

Return Value

(int) Returns 0 on success or a negative error code 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 3.0.0.
