APPLE_HIGH_DEFINITION_AUDIO_PLAY

typedef EFI_STATUS(EFIAPI * APPLE_HIGH_DEFINITION_AUDIO_PLAY) (IN APPLE_HIGH_DEFINITION_AUDIO_PROTOCOL *This, IN OUT UINTN *Arg1, IN OUT UINTN *Arg2, IN OUT UINTN *Arg3)

Definition at line 86 of file AppleHda.h.

APPLE_HIGH_DEFINITION_AUDIO_PLAY_TONE

typedef EFI_STATUS(EFIAPI * APPLE_HIGH_DEFINITION_AUDIO_PLAY_TONE) (IN APPLE_HIGH_DEFINITION_AUDIO_PROTOCOL *This, IN UINT32 ToneCount, IN UINTN ToneLength, IN UINTN SilenceLength, IN UINTN Frequency)

Generate cycles of beep signals with silence afterwards, blocking.

Parameters

[in]	This	This protocol instance.
[in]	ToneCount	Number of signals to produce.
[in]	ToneLength	Signal length in milliseconds.
[in]	SilenceLength	Silence length in milliseconds.
[in]	Frequency	Tone frequency, up to 44100 Hz, can be 0 for default.

Return values

EFI_SUCCESS	after signal completion.
EFI_SUCCESS	if ToneCount or ToneLength is 0.
