Detailed Description

Function Documentation

◆ jack_client_has_session_callback()

int jack_client_has_session_callback ( jack_client_t client,
const char *  client_name 

Find out whether a client has set up a session callback.

0 when the client has no session callback, 1 when it has one. -1 on error.

◆ jack_reserve_client_name()

int jack_reserve_client_name ( jack_client_t client,
const char *  name,
const char *  uuid 

Reserve a client name and associate it with a UUID.

When a client later calls jack_client_open() and specifies the UUID, jackd will assign the reserved name. This allows a session manager to know in advance under which client name its managed clients will appear.

0 on success, otherwise a non-zero error code

◆ jack_session_commands_free()

void jack_session_commands_free ( jack_session_command_t cmds)

Free the memory allocated by a session command.

◆ jack_session_notify()

jack_session_command_t* jack_session_notify ( jack_client_t client,
const char *  target,
jack_session_event_type_t  type,
const char *  path 

Send an event to all clients listening for session callbacks.

The returned strings of the clients are accumulated and returned as an array of jack_session_command_t. its terminated by ret[i].uuid == NULL target == NULL means send to all interested clients. otherwise a clientname
