References pw_loop::loop.

pw_data_loop_in_thread()

bool pw_data_loop_in_thread

(

struct pw_data_loop *

loop

)

Check if the current thread is the processing thread.

pw_data_loop_invoke()

int pw_data_loop_invoke	(	struct pw_data_loop *	loop,
		spa_invoke_func_t	func,
		uint32_t	seq,
		const void *	data,
		size_t	size,
		bool	block,
		void *	user_data
	)

invoke func in the context of the thread or in the caller thread when the loop is not running.

Since 0.3.3

References pw_loop::loop, pw_loop_invoke, res, and seq.

pw_data_loop_new()

struct pw_data_loop* pw_data_loop_new
