This method gets extended information about a field.

Syntax

HRESULT GetExtendedInfo( 
   REFGUID guidExtendedInfo,
   BYTE**  prgBuffer,
   DWORD*  pdwLen
);

int GetExtendedInfo(
   ref Guid guidExtendedInfo,
   IntPtr[] prgBuffer,
   ref uint pdwLen
);

Parameters

guidExtendedInfo
[in] Selects the information to be returned. Valid values are:

Value Description
guidConstantValue The value as a sequence of bytes.
guidConstantType The type as a type signature.

prgBuffer
[out] Returns the extended information.

pdwLen
[in, out] Returns the size of the extended information, in bytes.

Return Value

If successful, returns S_OK; otherwise, returns an error code.

Remarks

Currently, this method returns only the type or value of a constant. The caller must free the buffer returned in prgBuffer by calling COM's CoTaskMemFree function (C++) or FreeCoTaskMem (C#).
