DispatchState Structure

The DispatchState structure is used to transfer state to the IExecutionContext::Dispatch method. It describes the circumstances under which the Dispatch method is invoked on an IExecutionContext interface.

Syntax

struct DispatchState;

Members

Public Constructors

Name	Description
DispatchState::DispatchState	Constructs a new DispatchState object.

Public Data Members

Name	Description
DispatchState::m_dispatchStateSize	Size of this structure, which is used for versioning.
DispatchState::m_fIsPreviousContextAsynchronouslyBlocked	Tells whether this context has entered the Dispatch method because the previous context asynchronously blocked. This is used only on the UMS scheduling context, and is set to the value 0 for all other execution contexts.
DispatchState::m_reserved	Bits reserved for future information passing.
