/*++ /* NAME /* lmtp_session 3 /* SUMMARY /* LMTP_SESSION structure management /* SYNOPSIS /* #include "lmtp.h" /* /* LMTP_SESSION *lmtp_session_alloc(stream, host, addr, dest, type) /* VSTREAM *stream; /* const char *host; /* const char *addr; /* const char *dest; /* int type; /* /* LMTP_SESSION *lmtp_session_free(session) /* LMTP_SESSION *session; /* DESCRIPTION /* This module maintains information about connections, including /* per-peer debugging. /* /* lmtp_session_alloc() allocates memory for an LMTP_SESSION structure /* and initializes it with the given stream and host name and address /* information. The host name and address strings are copied. /* The type argument specifies the transport type. The dest argument /* specifies a string-valued name for the remote endpoint. /* If the peer name or address matches the debug-peer_list configuration /* parameter, the debugging level is incremented by the amount specified /* in the debug_peer_level parameter. /* /* lmtp_session_free() destroys an LMTP_SESSION structure and its /* members, making memory available for reuse. The result value is /* convenient null pointer. The debugging level is restored to the /* value prior to the lmtp_session_alloc() call. /* LICENSE /* .ad /* .fi /* The Secure Mailer license must be distributed with this software. /* SEE ALSO /* debug_peer(3), increase logging for selected peers /* AUTHOR(S) /* Wietse Venema /* IBM T.J.
