/sockudp Command - mIRC
< mirc‎ | commands

The /sockudp command allows you to send data to a specific address at a specific port destination (See UDP sockets).

Note: if /sockudp fails, it sets $sock().wserr to the error value, and trigger on sockwrite with $sockerr set etc.


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


  • -b - Indicates that you are specifying the numbytes value which is the number of bytes you want send, the full line is sent otherwise
  • -n - Appens a $crlf to the line being sent if it's not a &binvar or if does not already end with a $crlf
  • -t - Forces mIRC to send anything beginning with a & as plain text
  • -k - Keeps the socket opened
  • -d - Means you have specified the ip address as the bind address
  • -u - Enables dual stack socket to support both ipv4 and ipv6 for the listening socket, if that is available, you must bind to an ipv6 ip address
  • -z - Wait for the data to be sent if any and then close the socket


  • [bindip] - If -d has been specified, the ip address you want to use as the bind address.
  • <name> - The sockname name.
  • [port] - If specified, the local port to use, otherwise mIRC choose one randomly.
  • <ipaddress> - The ip address you want to send to information to, use you localhost with -k to create a listening socket.
  • <port> - The port you want to send to information to, that's your listening port if you create a server.
  • [numbytes] - If -b has been specified, indicates the number of bytes you want to send.
  • [text|%var|&binvar] - If specified, the message you want to send, can be a binary variable. You don't want to specify that parameter if you create a server.

  ; 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.
  echo -ag Currnt Time/Date: $asctime($calc(%time - 2208988800), yyyy-mm-dd hh:nn:ss TT)
  ; Close the socket
  sockclose $sockname
