init

Declaration

virtual bool init(IOUserAudioDriver *in_driver, bool in_supports_prewarming, OSString *in_device_uid, OSString *in_model_uid, OSString *in_manufacturer_uid, uint32_t in_zero_timestamp_period);

Parameters

• in_driver:

  The Iouseraudiodriver that owns this object.

• in_supports_prewarming:

  A Boolean value that specifies whether the device supports prewarming I/O.

• in_device_uid:

  A pointer to an Osstring containing the device UID.

• in_model_uid:

  A pointer to an Osstring containing the module UID.

• in_manufacturer_uid:

  A pointer to an Osstring containing the manufacturer UID.

• in_zero_timestamp_period:

  A Uint32_t whose value indicates the number of sample frames the host can expect between successive timestamps returned from GetZeroTimeStamp(). In other words, if GetZeroTimeStamp() returns a sample time of x, the host can expect that the next valid timestamp it receives will be x + in_zero_timestamp_period.

Return Value

true if initialization succeeded; false otherwise.
