26 | * m_functions execute protocol messages on this server: | |
27 | * | |
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...). | |
33 | * | |
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. | |
37 | * | |
38 | * (!IsServer(cptr)) => (cptr == sptr), because | |
39 | * prefixes are taken *only* from servers... | |
40 | * | |
41 | * (IsServer(cptr)) | |
42 | * (sptr == cptr) => the message didn't | |
43 | * have the prefix. | |
44 | * | |
45 | * (sptr != cptr && IsServer(sptr) means | |
46 | * the prefix specified servername. (?) | |
47 | * | |
48 | * (sptr != cptr && !IsServer(sptr) means | |
49 | * that message originated from a remote | |
50 | * user (not local). | |
51 | * | |
52 | * combining | |
53 | * | |
54 | * (!IsServer(sptr)) means that, sptr can safely | |
55 | * taken as defining the target structure of the | |
56 | * message in this server. | |
57 | * | |
58 | * *Always* true (if 'parse' and others are working correct): | |
59 | * | |
60 | * 1) sptr->from == cptr (note: cptr->from == cptr) | |
61 | * | |
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 ] | |
66 | * | |
67 | * parc number of variable parameter strings (if zero, | |
68 | * parv is allowed to be NULL) | |
69 | * | |
70 | * parv a NULL terminated list of parameter pointers, | |
71 | * | |
72 | * parv[0], sender (prefix string), if not present | |
73 | * this points to an empty string. | |
74 | * parv[1]...parv[parc-1] | |
75 | * pointers to additional parameters | |
76 | * parv[parc] == NULL, *always* | |
77 | * | |
78 | * note: it is guaranteed that parv[0]..parv[parc-1] are all | |
79 | * non-NULL pointers. | |
