27 * m_functions execute protocol messages on this server:
29 * cptr is always NON-NULL, pointing to a *LOCAL* client
30 * structure (with an open socket connected!). This
31 * identifies the physical socket where the message
32 * originated (or which caused the m_function to be
33 * executed--some m_functions may call others...).
35 * sptr is the source of the message, defined by the
36 * prefix part of the message if present. If not
37 * or prefix not found, then sptr==cptr.
39 * (!IsServer(cptr)) => (cptr == sptr), because
40 * prefixes are taken *only* from servers...
43 * (sptr == cptr) => the message didn't
46 * (sptr != cptr && IsServer(sptr) means
47 * the prefix specified servername. (?)
49 * (sptr != cptr && !IsServer(sptr) means
50 * that message originated from a remote
55 * (!IsServer(sptr)) means that, sptr can safely
56 * taken as defining the target structure of the
57 * message in this server.
59 * *Always* true (if 'parse' and others are working correct):
61 * 1) sptr->from == cptr (note: cptr->from == cptr)
63 * 2) MyConnect(sptr) <=> sptr == cptr (e.g. sptr
64 * *cannot* be a local connection, unless it's
65 * actually cptr!). [MyConnect(x) should probably
66 * be defined as (x == x->from) --msa ]
68 * parc number of variable parameter strings (if zero,
69 * parv is allowed to be NULL)
71 * parv a NULL terminated list of parameter pointers,
73 * parv[0], sender (prefix string), if not present
74 * this points to an empty string.
75 * parv[1]...parv[parc-1]
76 * pointers to additional parameters
77 * parv[parc] == NULL, *always*
79 * note: it is guaranteed that parv[0]..parv[parc-1] are all
