<p>
This creates a new port for the client.
<p>
A port is an object used for moving data in or out of the client. the data may be of any type. Ports may be connected to each other in various ways.
<p>
A port has a short name, which may be any non-NULL and non-zero length string, and is passed as the first argument. A port's full name is the name of the client concatenated with a colon (:) and then its short name.
<p>
A port has a type, which may be any non-NULL and non-zero length string, and is passed as the second argument. For types that are not built into the jack API (currently just JACK_DEFAULT_AUDIO_TYPE) the client MUST supply a non-zero size for the buffer as for @buffer_size. For builtin types, @buffer_size is ignored.
<p>
The @flags argument is formed from a bitmask of JackPortFlags values. </td>

The port latency is zero by default. Clients that control physical hardware with non-zero latency should call this to set the latency to its correct value. Note that the value should include any systemic latency present "outside" the physical hardware controlled by the client. For example, for a client controlling a digital audio interface connected to an external digital converter, the latency setting should include both buffering by the audio interface *and* the converter. </td>

A client may call this on a pair of its own ports to semi-permanently wire them together. This means that a client that wants to direct-wire an input port to an output port can call this and then no longer have to worry about moving data between them. Any data arriving at the input port will appear automatically at the output port.
<p>
The 'destination' port must be an output port. The 'source' port must be an input port. Both ports must belong to the same client. You cannot use this to tie ports between clients. That is what a connection is for. </td>
