This is activated whenever you receive a raw message from a tcp connection established with $CONNECT(). The parameters for the action are as follows:
$0 file descriptor for the connection.
$1 host name in connection
$2 code as listed below
$3- data or port number depending on code.
Incoming messages can be intercepted with ON DCC_RAW, which has the following formats:
fd host D data
fd host C
fd host N port
fd host E port
The D message indicates incoming data. The C message indicates that the socket has been closed. The N message indicates that a socket listening on the specified port has accepted a connection. fd in this case is the file descriptor for the new connection. The E message is generated when a CONNECT() results in a successful connection.
Conventions to be used for the socket access:
Scripts using sockets should never use the
serial number 0 in their hooks. As their first
act before using the DCC_RAW hooks, they should
set:
ON ^DCC_RAW * #
To ensure that all raw DCC sockets produce no
output.
A new set of hooks should be created for each
active socket at a chosen serial number. One
must always exist to detect the close message,
and as its last act must remove all the hooks
for that file descriptor.
