completed_frame_count()

uint64_t MayaFlux::Core::BackendWindowHandler::completed_frame_count ( const WindowRenderContext &  ctx ) const

private

Submitted frames of a window whose GPU work has finished.

Parameters

ctx	Window render context

Never blocks. A slot reset for acquisition but not yet resubmitted holds the id of its previous, finished submission, so the result can only understate completion.
