fIncludeChildren
Type: Int32

[in] If true, then the subcontext associated with the context bag is included. If false, then the subcontext is excluded.

pUsage
Type: array<Microsoft.VisualStudio.Shell.Interop.VSUSERCONTEXTATTRIBUTEUSAGE[]

[out] Specifies whether an attribute or keyword is located at the specified index position in the context bag. For a list of pUsage values, see VSUSERCONTEXTATTRIBUTEUSAGE.

Return Value

Type: Int32

Remarks

COM Signature

From context.idl:

HRESULT IVsUserContext::GetAttrUsage(
   [in] int index,
   [in] BOOL fIncludeChildren,
   [out, retval] VSUSERCONTEXTATTRIBUTEUSAGE * pUsage);

Use the IVsUserContext.GetAttrUsage method to determine whether keywords returned from the GetAttribute or GetAttributePri methods are F1 or lookup keywords.

The value of the fIncludeChildren parameter has no effect if the context bag does not have any subcontext.
