Member Function Documentation

createFence()

virtual FenceHandle Cogs::ISyncObjects::createFence ( )

pure virtual

Create a new fence object.

isFenceSignalled()

virtual bool Cogs::ISyncObjects::isFenceSignalled ( FenceHandle  fenceHandle )

pure virtual

Poll to see if a fence has been signalled.

Parameters

fenceHandle

valid fence handle.

Returns

True if fence is signalled.

releaseFence()

virtual void Cogs::ISyncObjects::releaseFence ( FenceHandle  fenceHandle )

pure virtual

Release an existing fence object.

resetFence()

virtual void Cogs::ISyncObjects::resetFence ( FenceHandle  fenceHandle )

pure virtual

Explicitly set fence into unsignalled state unsignalled.

Parameters

fenceHandle

valid fence handle.

waitFence()

virtual bool Cogs::ISyncObjects::waitFence ( FenceHandle  fenceHandle, uint32_t  timeout_ms  )

pure virtual

Try to let CPU wait for a fence to be signalled.

Note

The function might wait less than the specified timeout, even though the fence was not signalled.

On backends that prohibit blocking, this function will poll the fence status.

Parameters

fenceHandle	valid fence handle.
timeout_ms	Maximum amount of time to wait.

Returns

True if fence is signalled.
