|
|
* identifies the physical socket where the message
|
|
* originated (or which caused the m_function to be
|
|
* executed--some m_functions may call others...).
|
|
*
|
|
* sptr is the source of the message, defined by the

|
|
* (sptr == cptr) => the message didn't
|
|
* have the prefix.
|
|
*
|
|
* (sptr != cptr && IsServer(sptr) means
|
|
* the prefix specified servername. (?)
|
|
*
|
|
* (sptr != cptr && !IsServer(sptr) means
|

|
|
* user (not local).
|
|
*
|
|
* combining
|
|
*
|
|
* (!IsServer(sptr)) means that, sptr can safely
|
|
* taken as defining the target structure of the
|
|
* message in this server.
|
|
*
|
|
* *Always* true (if 'parse' and others are working correct):
|
|
*
|
|
* 1) sptr->from == cptr (note: cptr->from == cptr)
|
|
*
|
|
* 2) MyConnect(sptr) <=> sptr == cptr (e.g. sptr
|
|
* *cannot* be a local connection, unless it's
|
|
* actually cptr!). [MyConnect(x) should probably
|
|
* be defined as (x == x->from) --msa ]
|
|
*
|
|
* parc number of variable parameter strings (if zero,
|
|
* parv is allowed to be NULL)
|
|
*
|
|
* parv a NULL terminated list of parameter pointers,
|
|
*
|
|
* parv[0], sender (prefix string), if not present
|
|
* this points to an empty string.
|
|
* parv[1]...parv[parc-1]
|
|
* pointers to additional parameters
|
|
* parv[parc] == NULL, *always*
|
|
*

|
|
* non-NULL pointers.
