$serverctl(REFNUM <server refnum>)
$serverctl(GET <refnum> <param>)
$serverctl(SET <refnum> <param> <val>)
This function is a low-level interface to the client's server structure.
The REFNUM operation takes a server refnum, and returns that refnum if the refnum is valid, or returns the empty string if the refnum is invalid.
The REFNUM operation takes a regular old server description, but only the first two fields are used. The first field should contain a wildcard pattern that will match either an “ourname”, an “itsname”, a group, or an alternate name. If you specify a port number, then the server has to match the port number as well as the host. The operation returns a refnum to an open server if it can, and to a closed server if it must. It returns the empty string if nothing is found.
The REFNUM operation can take a port after the server name, and then any server must match the port as well as the server name. Normally the port is ignored.
The OMATCH, IMATCH, and GMATCH operations match a wildcard pattern against each server's “ourname”, “itsname”, and “groupname” respectively. The return value is a space separated list of server refnums that match.
The LAST_SERVER operation returns the refnum of the last irc server that sent us some data. This cannot be changed by the user.
The FROM_SERVER operation returns the current operative server. This can be changed by the user with XEVAL -s.
The MAX operation returns the highest server refnum in use. This can be used to bound a loop to iterate over all servers.
The ALLGROUPS operation returns a unique word list of all of the server groups that are in use. At this time, this operation does not take any arguments, but that will probably change in the future. You should not pass any arguments to this operation for now.
The GET and SET operations read and write respectively, attributes about a server refnum. Server refnum -1 always refers to the FROM_SERVER.
