SDL_LowerBlit

Perform low-level surface blitting only.

Header File

Defined in SDL_surface.h

Syntax

int SDL_LowerBlit
    (SDL_Surface * src, SDL_Rect * srcrect,
     SDL_Surface * dst, SDL_Rect * dstrect);

Function Parameters

SDL_Surface *	src	the SDL_Surface structure to be copied from.
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.
SDL_Rect *	dstrect	the SDL_Rect structure representing the rectangle that is copied into.

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.

Unless you know what you're doing, you should be using SDL_BlitSurface() instead.

Version

This function is available since SDL 2.0.0.
