// Function: TcpipNameListInsertIdx
//
// Purpose: Whenever a TCP/IP item needs to inserted into a specific position
// in a list this function needs to be called. It checks for a duplicate.
// If one exists, it removes it and then does the insertion. Subnet masks
// should not use this function because duplicates are allowed for them.
//
// Arguments:
// IN OUT NAMELIST* TcpipNameList - namelist to add to
// IN TCHAR* pString - string to add (input)
// IN UINT idx - 0-based index on where to do the insertion
//
// Returns: if a duplicate was removed the index where the duplicate was,
// -1 if there was no duplicate
//
//----------------------------------------------------------------------------

//
// Purpose: Whenever a TCP/IP item needs to inserted at the end of a list
// this function needs to be called. It checks for a duplicate. If one
// exists, it removes it and then does the insertion. Subnet masks should
// not use this function because duplicates are allowed for them.

// IN TCHAR* pString - string to add (input)
