resolve_pending_dispatch()

bool MayaFlux::Buffers::ShaderProcessor::resolve_pending_dispatch

(

bool

block

)

Resolve an outstanding asynchronous submission.

Parameters

block

True to wait for the fence, false to return immediately when it is not yet signaled.

Returns

True if a submission was resolved by this call.

On resolution invokes on_dispatch_complete, then release_fence, which also frees the associated command buffer. Invoked with block=false at the top of processing_function and with block=true from cleanup.
