Field Documentation

pj_status_t(* pjmedia_aud_dev_factory_op::init)(pjmedia_aud_dev_factory *f)

Initialize the audio device factory.

Parameters:

f

The audio device factory.

pj_status_t(* pjmedia_aud_dev_factory_op::destroy)(pjmedia_aud_dev_factory *f)

Close this audio device factory and release all resources back to the operating system.

Parameters:

f

The audio device factory.

unsigned(* pjmedia_aud_dev_factory_op::get_dev_count)(pjmedia_aud_dev_factory *f)

Get the number of audio devices installed in the system.

Parameters:

f

The audio device factory.

pj_status_t(* pjmedia_aud_dev_factory_op::get_dev_info)(pjmedia_aud_dev_factory *f, unsigned index, pjmedia_aud_dev_info *info)

Get the audio device information and capabilities.

Parameters:

	f	The audio device factory.
	index	Device index.
	info	The audio device information structure which will be initialized by this function once it returns successfully.

pj_status_t(* pjmedia_aud_dev_factory_op::default_param)(pjmedia_aud_dev_factory *f, unsigned index, pjmedia_aud_param *param)
