ITextStoreAnchor::RequestSupportedAttrs method (textstor.h)

Obtains the supported attributes of a text stream.

Syntax

HRESULT RequestSupportedAttrs(
  [in] DWORD           dwFlags,
  [in] ULONG           cFilterAttrs,
  [in] const TS_ATTRID *paFilterAttrs
);

Parameters

[in] dwFlags

Specifies whether a subsequent call to the ITextStoreAnchor::RetrieveRequestedAttrs method will contain the supported attributes. If the TS_ATTR_FIND_WANT_VALUE flag is specified, the default attribute values will be those in the TS_ATTRVAL structure after the subsequent call to ITextStoreAnchor::RetrieveRequestedAttrs. If any other flag is specified for this parameter, the method only verifies that the attribute is supported and that the varValue member of the TS_ATTRVAL structure is set to VT_EMPTY.

[in] cFilterAttrs

Specifies the number of supported attributes to obtain.

[in] paFilterAttrs

Pointer to the TS_ATTRID data type that specifies the attribute to verify. The method returns only the attributes specified by TS_ATTRID, even though other attributes might be supported.

Return value

This method can return one of these values.
