CONNECTDATA structure (ocidl.h)

  • Článek

Describes a connection that exists to a given connection point.

Syntax

typedef struct tagCONNECTDATA {
  IUnknown *pUnk;
  DWORD    dwCookie;
} CONNECTDATA, *PCONNECTDATA, *LPCONNECTDATA;

Members

pUnk

A pointer to the IUnknown interface on a connected advisory sink. The caller must call Release using this pointer when the CONNECTDATA structure is no longer needed. The caller is responsible for calling Release for each CONNECTDATA structure enumerated through IEnumConnections::Next.

dwCookie

Connection where this value is the same token that is returned originally from calls to IConnectionPoint::Advise. This token can be used to disconnect the sink pointed to by a pUnk by passing dwCookie to IConnectionPoint::Unadvise.
