NAME¶

SDL_GetRenderMetalCommandEncoder - Get the Metal command encoder for the current frame.

HEADER FILE¶

Defined in SDL3/SDL_render.h

SYNOPSIS¶

#include "SDL3/SDL.h"

void * SDL_GetRenderMetalCommandEncoder(SDL_Renderer *renderer);

DESCRIPTION¶

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!

FUNCTION PARAMETERS¶

renderer

the renderer to query.

RETURN VALUE¶

Returns an id<MTLRenderCommandEncoder> on success, or NULL if the renderer isn't a Metal renderer or there was an error.

THREAD SAFETY¶

You may only call this function from the main thread.

AVAILABILITY¶

This function is available since SDL 3.1.3.
