Parameters
dwHint
Type: System.UInt32[in] Value indicating whether this is a typical idle-time update of the context bag or a request for F1 Help. For a list of dwHint values, see LanguageContextHint.
pBuffer
Type: Microsoft.VisualStudio.TextManager.Interop.IVsTextLines[in] Text buffer in question.
ptsSelection
Type: array<Microsoft.VisualStudio.TextManager.Interop.TextSpan[][in] Relevant range of text within the buffer (that is, the context).
pUC
Type: System.Object[in, out] Pointer to the context bag on the Visual Studio core text editor.
Return Value
Type: System.Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.
Remarks
COM Signature
From textmgr.idl:
HRESULT IVsLanguageContextProvider::UpdateLanguageContext(
DWORD dwHint,
IVsTextLines *pBuffer,
TextSpan *ptsSelection
);
UpdateLanguageContext return values:
S_OK: the implementer has added whatever context should be added.
Any other success code: forbidden (caller will assert).
Any failure code: means the implementer is "passing" on this opportunity to provide context and the text editor will fall back to other mechanisms.
