26 * m_functions execute protocol messages on this server:
28 * cptr is always NON-NULL, pointing to a *LOCAL* client
29 * structure (with an open socket connected!). This
30 * identifies the physical socket where the message
31 * originated (or which caused the m_function to be
32 * executed--some m_functions may call others...).
34 * sptr is the source of the message, defined by the
35 * prefix part of the message if present. If not
36 * or prefix not found, then sptr==cptr.
38 * (!IsServer(cptr)) => (cptr == sptr), because
39 * prefixes are taken *only* from servers...

45 * (sptr != cptr && IsServer(sptr) means
46 * the prefix specified servername. (?)
48 * (sptr != cptr && !IsServer(sptr) means
49 * that message originated from a remote
54 * (!IsServer(sptr)) means that, sptr can safely
55 * taken as defining the target structure of the
56 * message in this server.
58 * *Always* true (if 'parse' and others are working correct):
60 * 1) sptr->from == cptr (note: cptr->from == cptr)
62 * 2) MyConnect(sptr) <=> sptr == cptr (e.g. sptr
63 * *cannot* be a local connection, unless it's
64 * actually cptr!). [MyConnect(x) should probably
65 * be defined as (x == x->from) --msa ]
67 * parc number of variable parameter strings (if zero,
68 * parv is allowed to be NULL)
70 * parv a NULL terminated list of parameter pointers,
72 * parv[0], sender (prefix string), if not present
73 * this points to an empty string.

76 * parv[parc] == NULL, *always*
