32 + * m_functions execute protocol messages on this server:
33 + * int m_func(struct Client* client_p, struct Client* source_p, int parc, char* parv[]);
34 + *
35 + *    client_p    is always NON-NULL, pointing to a *LOCAL* client
36 + *            structure (with an open socket connected!). This
37 + *            identifies the physical socket where the message
38 + *            originated (or which caused the m_function to be
39 + *            executed--some m_functions may call others...).
40 + *
41 + *    source_p    is the source of the message, defined by the
42 + *            prefix part of the message if present. If not
43 + *            or prefix not found, then source_p==client_p.
44 + *
45 + *            (!IsServer(client_p)) => (client_p == source_p), because
46 + *            prefixes are taken *only* from servers...
47 + *
48 + *            (IsServer(client_p))
49 + *                    (source_p == client_p) => the message didn't
50 + *                    have the prefix.
51 + *
52 + *                    (source_p != client_p && IsServer(source_p) means
53 + *                    the prefix specified servername. (?)
54 + *
55 + *                    (source_p != client_p && !IsServer(source_p) means
56 + *                    that message originated from a remote
57 + *                    user (not local).
58 + *
59 + *
60 + *            combining
61 + *
62 + *            (!IsServer(source_p)) means that, source_p can safely
63 + *            taken as defining the target structure of the
64 + *            message in this server.
65 + *
66 + *    *Always* true (if 'parse' and others are working correct):
67 + *
68 + *    1)      source_p->from == client_p  (note: client_p->from == client_p)
69 + *
70 + *    2)      MyConnect(source_p) <=> source_p == client_p (e.g. source_p
71 + *            *cannot* be a local connection, unless it's
72 + *            actually client_p!). [MyConnect(x) should probably
73 + *            be defined as (x == x->from) --msa ]
74 + *
75 + *    parc    number of variable parameter strings (if zero,
76 + *            parv is allowed to be NULL)
77 + *
78 + *    parv    a NULL terminated list of parameter pointers,
79 + *
80 + *                    parv[0], sender (prefix string), if not present
81 + *                            this points to an empty string.
82 + *                    parv[1]...parv[parc-1]
83 + *                            pointers to additional parameters
84 + *                    parv[parc] == NULL, *always*
85 + *
86 + *            note:   it is guaranteed that parv[0]..parv[parc-1] are all
87 + *                    non-NULL pointers.
