Detailed Description

This demonstrates the basic concepts for writing a client that runs within the JACK server process.

For the sake of example, a port_pair_t is allocated in jack_initialize(), passed to inprocess() as an argument, then freed in jack_finish().

Function Documentation

int inprocess (  jack_nframes_t  nframes, void *  arg )

Called in the realtime thread on every process cycle. The entry point name was passed to jack_set_process_callback() from jack_initialize(). Although this is an internal client, its process() interface is identical to simple_client.c. Returns: 0 if successful; otherwise jack_finish() will be called and the client terminated immediately.

void jack_finish (  void *  arg  )

This required entry point is called immediately before the client is unloaded, which could happen due to a call to jack_internal_client_unload(), or a nonzero return from either jack_initialize() or inprocess(). Parameters: arg  the same parameter provided to inprocess().

int jack_initialize (  jack_client_t *  client, const char *  load_init )

This required entry point is called after the client is loaded by jack_internal_client_load(). Parameters: client  pointer to JACK client structure. load_init  character string passed to the load operation. Returns: 0 if successful; otherwise jack_finish() will be called and the client terminated immediately.
