/*
 * ipc_s.h for HP-UX 10.30 and above
 *
 * This header file defines the ipc_s structure for lsof.  The ipc_s structure
 * is the streams equivalent of a Berkeley-style inpcb (Internet Protocol
 * Control Block).  The ipc_s holds the TCP/IP address for a stream.
 *
 * The original HP-UX 11 distribution has a flat ipc_s structure, with hash
 * links to other ipc_s structures, and direct links to the the read and write
 * sections of the stream.
 *
 * After patch bundle B11.00.43 the ipc_s structure definition requires
 * two other Q4-derived structures, mirg_s and ipis_s.  The ipis_s structure
 * contains the hash and stream links formerly contained in ipc_s.
