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.
