sdlSetRenderTarget function

int sdlSetRenderTarget(Pointer<SdlRenderer> renderer, Pointer<SdlTexture> texture)

Set a texture as the current rendering target.

Before using this function, you should check the SDL_RENDERER_TARGETTEXTURE bit in the flags of SDL_RendererInfo to see if render targets are supported.

The default render target is the window for which the renderer was created. To stop rendering to a texture and render to the window again, call this function with a NULL texture.

\param renderer the rendering context \param texture the targeted texture, which must be created with the SDL_TEXTUREACCESS_TARGET flag, or NULL to render to the window instead of a texture. \returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

\since This function is available since SDL 2.0.0.
