ITextStoreAnchor::RequestAttrsTransitioningAtPosition method (textstor.h)

Obtains a list of attributes that begin or end at the specified anchor ___location.

Syntax

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

Parameters

[in] paPos

Pointer to the anchor.

[in] cFilterAttrs

Specifies the number of attributes to obtain.

[in] paFilterAttrs

Pointer to the TS_ATTRID data type that specifies the attribute to verify.

[in] dwFlags

Specifies attributes for the call to the ITextStoreAnchor::RetrieveRequestedAttrs method. If this parameter is not set, the method returns the attributes that start at the specified anchor ___location. Other possible values for this parameter are the following.

Value Meaning
TS_ATTR_FIND_WANT_END
Obtains the attributes that end at the specified anchor ___location.
TS_ATTR_FIND_WANT_VALUE
Obtains the value of the attribute in addition to the attribute. The attribute value is put into the varValue member of the TS_ATTRVAL structure during the ITextStoreAnchor::RetrieveRequestedAttrs method call.

Return value

This method can return one of these values.

Value Description
S_OK
The method was successful.
E_INVALIDARG
paPos is invalid.

Remarks

In the sentence, "This is italic text.", the italic attribute starts before the word italic and ends after the word text.

If the flag TS_ATTR_FIND_WANT_END is set in dwFlags, the method would return the italic attribute for the text "italic <anchor>normal", because there is an end transition at the anchor ___location.
