Get the current frequency range. It also returns the minimum and maximum frequencies (Hz) for the returned range. Client should always use the minimum and maximum frequencies returned by the tuner device, since it may vary slightly depending on the hardware.

Get the maximum possible signal strength of a tuned frequency.

Get the signal strenth of the currently tuned frequency.

Get the current squelching (muting in frequencies without reception) setting.

Get the current frequency's stereo mode (stereo or mono).

Factory function to create a new instance of the FM tuner.

Asynchronous request to get control of the FM tuner. This method call must be made before any other method calls in this API. User must be ready to receive callback method MrftoRequestTunerControlComplete. Control to the tuner must be granted before any functions that require control of the tuner (such as SetFrequency) can be made. The only API call that doesn't require tuner control to be granted is EnableTunerInOfflineMode().

Asynchronous request to tune the tuner to the speficied frequency (Hz). User must be ready to receive callback method MrftoTuneComplete.

Asynchronous request to set the frequency range. User must be ready to receive callback method MrftoSetFrequencyRangeComplete. If not set, it will be defaulted to EFmRangeEuroAmerica.

Set the current squleching (muting in frequencies without reception) setting. Squelching is enabled by default.

Asynchronous request to find a radio station, starting from the currently tuned frequency and searching in the direction specified (i.e. up or down). User must be ready to receive callback method MrftoSeekComplete. The station found is returned in the callback.

If no station is found after a complete loop, seek will stop and return KErrNotfound in the callback method and frequency will not change.
