/**
 * The NtCreateWorkerFactory routine creates a worker factory object that manages a pool of worker threads bound to an I/O completion port.
 *
 * \param WorkerFactoryHandleReturn A pointer to a variable that receives a handle to the new worker factory object.
 * \param DesiredAccess The access mask that specifies the requested access to the worker factory object.
 * \param ObjectAttributes A pointer to an OBJECT_ATTRIBUTES structure that specifies the object attributes. This parameter is optional.
 * \param CompletionPortHandle A handle to the I/O completion port that the worker factory is associated with.
 * \param WorkerProcessHandle A handle to the process in which the worker threads are created.
 * \param StartRoutine A pointer to the routine that is executed by each worker thread.
 * \param StartParameter A pointer to the parameter passed to the start routine. This parameter is optional.
 * \param MaxThreadCount The maximum number of worker threads that the factory can create. This parameter is optional.
 * \param StackReserve The amount of stack space to reserve for each worker thread, in bytes. This parameter is optional.
 * \param StackCommit The amount of stack space to commit for each worker thread, in bytes. This parameter is optional.
 * \return NTSTATUS Successful or errant status.
