None.

Notes:

This table entry is specifically returned by a call to GetExtendedTcpTable with the TableClass parameter set to a TCP_TABLE_OWNER_PID_* value from the TCP_TABLE_CLASS enumeration and the ulAf parameter set to AF_INET4.

Ports are broken up by byes because of the way they are returned. (This is the same as the standard library does it).

High order by is returned first. Port 139 would be represented as localPort1 =0, localPort2=139, localPort3=0, localPort4=0,

where as 5800 would be localPort1=22, localPort2=168, etc..., MSDN shows these as being DWORD.
