40 * m_functions execute protocol messages on this server:
42 * cptr is always NON-NULL, pointing to a *LOCAL* client
43 * structure (with an open socket connected!). This
44 * identifies the physical socket where the message
45 * originated (or which caused the m_function to be
46 * executed--some m_functions may call others...).
48 * sptr is the source of the message, defined by the
49 * prefix part of the message if present. If not
50 * or prefix not found, then sptr==cptr.
52 * (!IsServer(cptr)) => (cptr == sptr), because
53 * prefixes are taken *only* from servers...
56 * (sptr == cptr) => the message didn't
59 * (sptr != cptr && IsServer(sptr) means
60 * the prefix specified servername. (?)
62 * (sptr != cptr && !IsServer(sptr) means
63 * that message originated from a remote
68 * (!IsServer(sptr)) means that, sptr can safely
69 * taken as defining the target structure of the
70 * message in this server.
72 * *Always* true (if 'parse' and others are working correct):
74 * 1) sptr->from == cptr (note: cptr->from == cptr)
76 * 2) MyConnect(sptr) <=> sptr == cptr (e.g. sptr
77 * *cannot* be a local connection, unless it's
78 * actually cptr!). [MyConnect(x) should probably
79 * be defined as (x == x->from) --msa ]
81 * parc number of variable parameter strings (if zero,
82 * parv is allowed to be NULL)
84 * parv a NULL terminated list of parameter pointers,
86 * parv[0], sender (prefix string), if not present
87 * this points to an empty string.
88 * parv[1]...parv[parc-1]
89 * pointers to additional parameters
90 * parv[parc] == NULL, *always*
92 * note: it is guaranteed that parv[0]..parv[parc-1] are all
