## OSCbundle

OSCbundle — Sends data to other processes using the OSC protocol by packing messages in a bundle.

## Description

Uses the OSC protocol to send one or more messages to other OSC listening processes in a single bundle. Unlike OSCsend, it can be used to send multiple messages at the same time, but only standard OSC numeric types are allowed.

## Syntax

    OSCbundle kwhen, ihost, iport,
        Sdest[], Stype[],kArgs[][][,isize]

## Initialization

ihost -- a string that is the intended host computer domain name. An empty string is interpreted as the current computer.

iport -- the number of the port that is used for the communication.

isize -- maximum packet size in bytes, defaults to 65536.

## Performance

kwhen -- a bundle of messages is sent whenever this value changes. A message will always be sent on the first call.

Sdest[] -- an array of strings containing the destination address for each message. Length must agree with Stype[].

Stype[] -- an array of strings containing the types for each message. Only numeric types ('i' for integers and 'f' for floats) are supported. Length must agree with Sdest[].

kArg[][] -- a two-dimensional array containing the arguments for each message. Its dimension 1 (number of rows) must agree with Sdest[] and Stype[]. Its dimension 2 (number of columns) must be large enough to accommodate the message with the largest number of arguments. Each row should contain the arguments for the types of each message. If a row contains fewer arguments, any remaining data items are filled with zeros. Arguments in excess of what each type string requires are ignored.

## Example

Here is an example of the OSCBundle opcode. It uses the file oscbundle.csd.
