Format

sockinfo effectiveaddress TypeOfAddress[-d]

Parameters

Item Description
effectiveaddress Specifies the effective address of the structure to be displayed.
TypeOfAddress Identifies the type of structure to which the effective address points. Valid address types are unpcb, inpcb, rawcb, ripcb, sctpcb, socket, and tcpcb.
-d Suppresses the display of send and receive buffer information for a socket.
