Get the Metal command encoder for the current frame.
Defined in <SDL3/SDL_render.h>
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.
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!
This function is available since SDL 3.0.0.
