IVsRunningDocumentTable4::GetDocumentEditLockCount Method (UInt32)

This is functionally identical to calling IVsRunningDocumentTable.GetDocumentInfo and requesting only the edit lock count, but it is easier to consume from managed code. In managed code it is impossible to request the flags without also requesting all of the other information, and requesting all of the other information can result in the potentially unnecessary initialization of an RDT_PendingInitialization document.
