sdlGetRenderMetalCommandEncoder function render

Pointer<NativeType> sdlGetRenderMetalCommandEncoder(Pointer<SdlRenderer> renderer)

Get the Metal command encoder for the current frame.

This function returns void *, so SDL doesn't have to include Metal's headers, but it can be safely cast to an id<MTLRenderCommandEncoder>.

This will return NULL if Metal refuses to give SDL a drawable to render to, which might happen if the window is hidden/minimized/offscreen. This doesn't apply to command encoders for render targets, just the window's backbuffer. Check your return values!

\param renderer the renderer to query. \returns an id<MTLRenderCommandEncoder> on success, or NULL if the renderer isn't a Metal renderer or there was an error.

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

\since This function is available since SDL 3.2.0.
