udpsend

Send Max messages over a network using UDP

Description

udpsend transmits messages over a network using the User Datagram Protocol.

Arguments

Name Type Opt Description
local-host-name or IP symbol Obligatory. Specifies the host destination to which messages will be sent over a network. Host destinations can be specified either by name (e.g., localhost) or by IP address (e.g., 127.0.0.1).
remote-port int Obligatory. Specifies the remote port that the udpsend object will use when sending messages.

Messages

bang Sends the bang message over the network using UDP.
int message [int]
Sends an int message over the network using UDP.
float message [float]
Sends a float message over the network using UDP.
list message [list]
Sends a list message over the network using UDP.
anything message [list]
Sends the given message over the network using UDP.
FullPacket behavior-flag (0 or 1) [int]
number [int]
The udpsend object and its counterpart the udpreceive object provide support for third-party Max objects that work with the Open Sound Control (OSC) protocol developed by the Center for New Music and Audio Technologies (CNMAT) at the University of California, Berkeley. The FullPacket message toggles support for the 'FullPacket' message used by the CNMAT Open Sound Control externals or the Max udpreceive object--when set, the udpsend object will send UDP buffers in the form of OSC 'FullPacket' messages.
host local-host-name or IP [symbol]
The word host, followed by a symbol, specifies the host destination to which messages will be sent. Host destinations can be specified either by name (e.g., localhost) or by IP address (e.g., 127.0.0.1).
maxqueuesize maximum-messages [int]
The word maxqueuesize, followed by an integer, sets the maximum number of incoming messages that can be in the queue at any given time (default="2048)." The work queue will grow as needed until this maximum limit is reached. In high-traffic or high-speed situations, you may need to increase the maximum queue size to avoid dropped messages.
maxpacketsize maximum-packet-size [int]
The word maxpacketsize, followed by an integer, sets the size, in bytes, of the largest UDP packet that you can send (default="5096)." Since this value is related to the largest Max message you can possibly send, you may need to increase this value if you are sending very long Max messages.
port remote-port [int]
The word port, followed by a number, specifies the remote port that the udpsend object will use to send outgoing messages.

Information for box attributes common to all objects

Output

(UDP): There are no outlets. Max messages received by the udpsend obect are serialized and sent over the network as OSC-compatible UDP packets.
