AsyncBase::Close Method

Closes the asynchronous operation.

STDMETHOD(
   Close
)(void) override;

Return Value

S_OK if the operation closes or is already closed; otherwise, E_ILLEGAL_STATE_CHANGE.

Remarks

Close() is a default implementation of IAsyncInfo::Close, and does no actual work. To actually close an asynchronous operation, override the OnClose() pure virtual method.

Requirements

Header: async.h

Namespace: Microsoft::WRL
