Control an event loop.
| void(* spa_loop_control_methods::add_hook) (void *object, struct spa_hook *hook, const struct spa_loop_control_hooks *hooks, void *data) |
Add a hook.
| ctrl | the control to change |
| hooks | the hooks to add |
Adds hooks to the loop controlled by ctrl.
| void(* spa_loop_control_methods::enter) (void *object) |
Enter a loop.
| ctrl | the control |
Start an iteration of the loop. This function should be called before calling iterate and is typically used to capture the thread that this loop will run in.
| int(* spa_loop_control_methods::get_fd) (void *object) |
| int(* spa_loop_control_methods::iterate) (void *object, int timeout) |
Perform one iteration of the loop.
| ctrl | the control |
| timeout | an optional timeout in milliseconds. 0 for no timeout, -1 for infinite timeout. |
This function will block up to timeout milliseconds and then dispatch the fds with activity. The number of dispatched fds is returned.
| void(* spa_loop_control_methods::leave) (void *object) |
Leave a loop.
| ctrl | the control |
Ends the iteration of a loop. This should be called after calling iterate.
