release_fence()

void MayaFlux::Portal::Graphics::ShaderFoundry::release_fence

(

FenceID

fence_id

)

Destroy the fence and free its associated command buffer.

Must be called once per FenceID returned by submit_async, after is_fence_signaled returns true. Failure to call this leaks a VkFence and a command buffer slot every dispatch cycle.

Safe to call with INVALID_FENCE.

Parameters

fence_id

FenceID returned by submit_async.
