sdlGetRenderDrawBlendMode function render

bool sdlGetRenderDrawBlendMode(
  1. Pointer<SdlRenderer> renderer,
  2. Pointer<Uint32> blendMode
)

Get the blend mode used for drawing operations.

\param renderer the rendering context. \param blendMode a pointer filled in with the current SDL_BlendMode. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety This function should only be called on the main thread.

\since This function is available since SDL 3.2.0.
