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