Typedef Documentation

typedef void(* hal_audio_stream_copy_callback_t) (hal_audio_event_t event, hal_audio_copy_stream_t *user_data)

This defines the audio stream copy callback function prototype.

Register a callback function while audio stream copy path is turned on. For more details about the callback, please refer to hal_audio_register_copied_stream_out_callback().

Parameters

[in]	event	is the value defined in hal_audio_event_t. This parameter is given by the driver to notify the user about the data flow processing behavior.
[in]	user_data	is a structure hal_audio_copy_stream_t contain stream out data and related information.

typedef void(* hal_audio_stream_in_callback_t) (hal_audio_event_t event, void *user_data)

This defines the audio stream in callback function prototype.

Register a callback function while audio stream in path is turned on. For more details about the callback, please refer to hal_audio_register_stream_in_callback().

Parameters

[in]	event	is the value defined in hal_audio_event_t. This parameter is given by the driver to notify the user about the data flow processing behavior.
[in]	user_data	is a user defined parameter provided by hal_audio_register_stream_in_callback() function.

typedef void(* hal_audio_stream_out_callback_t) (hal_audio_event_t event, void *user_data)

This defines the audio stream out callback function prototype.

Register a callback function while audio stream out path is turned on. For more details about the callback, please refer to hal_audio_register_stream_out_callback().

Parameters

[in]	event	is the value defined in hal_audio_event_t. This parameter is given by the driver to notify the user about the data flow processing behavior.
[in]	user_data	is a user defined parameter provided by hal_audio_register_stream_out_callback() function.
