[Mono-dev] [PATCH] Basic support for Marshal.GetHRForException

[Kornél Pál]

Hi,

Exception.HResult can be used to identify exceptions (for example
IOException). Unfortunately this is a protected property and is only exposed
by ExternalException.ErrorCode.

Marshal.GetHRForException should return this value in addition to calling
SetErrorInfo (COM support function). We have no COM interop support yet, so
I only implemented it as returning Exception.HResult.

Please review and approve the patch.
