## Detailed Description

STK internet streaming output class.

This WvOut subclass can stream data over a network via a TCP or UDP socket connection. The data is converted to big-endian byte order, if necessary, before being transmitted.

InetWvOut supports multi-channel data. It is important to distinguish the tick() method that outputs a single sample to all channels in a sample frame from the overloaded one that takes a reference to an StkFrames object for multi-channel and/or multi-frame data.

This class connects to a socket server, the port and IP address of which must be specified as constructor arguments. The default data type is signed 16-bit integers but any of the defined StkFormats are permissible.

## Constructor & Destructor Documentation

stk::InetWvOut::InetWvOut | ( | int | port,
|  | Socket::ProtocolType | protocol = `Socket::PROTO_TCP`,
|  | std::string | hostname = `"localhost"`,
|  | unsigned int | nChannels = `1`,
|  | Stk::StkFormat | format = `STK_SINT16`,
|  | unsigned long | packetFrames = `1024` |
| ) |  |  |

Overloaded constructor which opens a network connection during instantiation.

An StkError is thrown if a socket error occurs or an invalid argument is specified.

## Member Function Documentation

void stk::InetWvOut::connect | ( | int | port,
|  | Socket::ProtocolType | protocol = `Socket::PROTO_TCP`,
|  | std::string | hostname = `"localhost"`,
|  | unsigned int | nChannels = `1`,
|  | Stk::StkFormat | format = `STK_SINT16` |
| ) |  |  |

Connect to the specified host and port and prepare to stream nChannels of data in the given data format.

An StkError is thrown if a socket error occurs or an invalid argument is specified.

void stk::InetWvOut::tick | ( | const StkFloat | sample | ) | `[virtual]`

Output a single sample to all channels in a sample frame.

An StkError is thrown if an output error occurs. If a socket connection does not exist, the function does nothing (a warning will be issued if _STK_DEBUG_ is defined during compilation).

Implements stk::WvOut.

void stk::InetWvOut::tick | ( | const StkFrames & | frames | ) | `[virtual]`

Output the StkFrames data.

An StkError will be thrown if an output error occurs. An StkError will also be thrown if _STK_DEBUG_ is defined during compilation and there is an incompatability between the number of channels in the FileWvOut object and that in the StkFrames object. If a socket connection does not exist, the function does nothing (a warning will be issued if _STK_DEBUG_ is defined during compilation).

Implements stk::WvOut.
