/*
* tcp_s.h for HP-UX 10.30 and above
*
* This header file defines the TCP connection structure, tpc_s, for lsof.
* Lsof gets the parameters of a TCP connection from tcp_s. Lsof locates a
* tcp_s structure by scanning the queue structure chain of a TCP stream,
* looking for a queue structure whose module name begins with TCP; that queue
* structure's private data pointer, q_ptr, addresses its associated tcp_s
* structure.
