Detailed Description

Function Documentation

◆ jack_cycle_signal()

void jack_cycle_signal ( jack_client_t client,
int  status 
)

Signal next clients in the graph.

Parameters
client- pointer to a JACK client structure
status- if non-zero, calling thread should exit

◆ jack_cycle_wait()

jack_nframes_t jack_cycle_wait ( jack_client_t client)

Wait until this JACK client should process data.

Parameters
client- pointer to a JACK client structure
Returns
the number of frames of data to process

◆ jack_set_process_thread()

int jack_set_process_thread ( jack_client_t client,
JackThreadCallback  fun,
void *  arg 
)

Tell the Jack server to call thread_callback in the RT thread. Typical use are in conjunction with jack_cycle_wait and @ jack_cycle_signal functions. The code in the supplied function must be suitable for real-time execution. That means that it cannot call functions that might block for a long time. This includes all I/O functions (disk, TTY, network), malloc, free, printf, pthread_mutex_lock, sleep, wait, poll, select, pthread_join, pthread_cond_wait, etc, etc.

Returns
0 on success, otherwise a non-zero error code.

◆ jack_thread_wait()

jack_nframes_t jack_thread_wait ( jack_client_t ,
int  status 
)

THIS FUNCTION IS DEPRECATED AND SHOULD NOT BE USED IN NEW JACK CLIENTS

It should be replace by use of @ jack_cycle_wait and @ jack_cycle_signal functions.
