_Added in 2.3_

*/sockudp [-bntkdu] [bindip] <name> [port] <ipaddress> <port> [numbytes] [text|%var|&binvar]*

Opens a UDP connection to a remote ipaddress/port and sends a UDP packet.

*Switches*

-b - Indicates that you are specifying the numbytes value which is the number of bytes you want sent.

-n - Appends a [[$crlf]] to the line being sent if it is not a &binvar and if it does not already have a [[$crlf]].

-t - Forces AdiIRC to send anything beginning with a *&* as normal text instead of interpreting it as a binary variable.

-k - Forces the socket to stay open, so it can receive UDP data.

-d - The specified IP address is the bind ip address.

-u - Enables "dual stack sockets":https://docs.microsoft.com/en-us/windows/win32/winsock/dual-stack-sockets.

*Parameters*

[bindip] - Bind ip to be used.

<name> - Socket connection name.

[port] - Bind port to be used.

<ipaddress> - Remote ipaddress to connect to.

<port> - Remote port to connect to.

[numbytes] - Number of bytes to send. (used with -b)

[text|%var|&binvar] - Text, %variable or &binvar to send.

*Example*

<pre>

alias gettime {

  ; Set a NULL byte binary variable.

  bset &null 1 0

  ; Open a UDP connection to Time-a.nist.gov = 129.6.15.28

  sockudp -k gettime 129.6.15.28 37 &null

}

on *:udpread:gettime: {

  ; Read the reply.

  sockread -f &time

  var %time $bvar(&time,1,$bvar(&time,0))

  ; Convert to binary, remove spaces.

  var %bin $regsubex(%time, /(\d+)\s?/g, $base(\1, 10, 2, 8))

  ; Get the current unix time in decimal system.

  var %time = $base(%bin, 2, 10)

  ; Print the time and close the socket.

  echo -ag Currnt Time/Date: $asctime($calc(%time - 2208988800), yyyy-mm-dd hh:nn:ss TT)

  sockclose $sockname

}
