CreateAsyncBindCtx function (urlmon.h)

Creates an asynchronous bind context for use with asynchronous monikers.

Syntax

HRESULT CreateAsyncBindCtx(
  [in]  DWORD               reserved,
  [in]  IBindStatusCallback *pBSCb,
  [in]  IEnumFORMATETC      *pEFetc,
  [out] IBindCtx            **ppBC
);

Parameters

[in] reserved

This parameter is reserved and must be 0.

[in] pBSCb

A pointer to the IBindStatusCallback interface used for receiving data availability and progress notification.

[in] pEFetc

A pointer to the IEnumFORMATETC interface that can be used to enumerate formats for format negotiation during binding. This parameter can be NULL, in which case the caller is not interested in format negotiation during binding, and the default format of the object will be bound to.

[out] ppBC

Address of an IBindCtx* pointer variable that receives the interface pointer to the new bind context.

Return value

This function can return the following values.

Remarks

This function automatically registers the IBindStatusCallback and IEnumFORMATETC interfaces with the bind context. The client can specify flags from BSCO_OPTION to indicate which callback notifications the client is capable of receiving. If the client does not wish to receive certain notification, it can choose to implement those callback methods as empty function stubs (returning E_NOTIMPL), and they should not be called.

The RegisterBindStatusCallback function can also be used to register callback interfaces in the bind context.
