This function removes a format enumerator from the given bind context.

Syntax 

HRESULT RevokeFormatEnumerator(
  LPBC 
pbc,
  IEnumFORMATETC* 
pEFetc
);

Parameters

pbc

[in] Address of the IBindCtxinterface for the bind context from which the enumerator is to be revoked.

pEFetc

[in] Address of the IEnumFORMATETCinterface for the enumerator to revoke.

Return Value

Returns S_OK if the enumerator was successfully removed or E_INVALIDARG if one or more parameters are invalid.

Remarks

This function removes a format enumerator from the bind context specified in pbc. It must previously have been registered with a call to RegisterFormatEnumerator.

Note:
It is not necessary to make this call for every use of a bind context. It is possible, although not recommended, to reuse the same bind context and the same format enumerator for several bind operations. Upon calling Release, all registered objects on that bind context are revoked, including the format enumerator interfaces. Therefore, releasing a bind context implicitly releases all registered format enumerators. However, if you choose to reuse a bind context, you can use RevokeFormatEnumeratorto remove a registered format enumerator so it is not reused.
