TSPI_phoneSetRing (Windows Embedded CE 6.0)

1/6/2010

This function rings the specified open phone device using the specified ring mode and volume.

Syntax

LONG TSPIAPI TSPI_phoneSetRing(
  DRV_REQUESTID dwRequestID,  
  HDRVPHONE hdPhone, 
  DWORD dwRingMode, 
  DWORD dwVolume 
);

Parameters

• dwRequestID
  Identifier of the asynchronous request.

• hdPhone
  andle to the phone to be rung.

• dwRingMode
  Ringing pattern with which to ring the phone. This parameter must be within the range from zero through the value of the dwNumRingModes member in the PHONECAPS structure. If dwNumRingModes is zero, the ring mode of the phone cannot be controlled; if dwNumRingModes is 1, a value of zero for dwRingMode indicates that the phone should not be rung (silence), and other values from 1 through dwNumRingModes are valid ring modes for the phone device.

• dwVolume
  Volume level with which the phone is to be rung. This is a number in the range from 0x00000000 (silence) through 0x0000FFFF (maximum volume). The actual granularity and quantization of volume settings in this range are service-provider specific. A value for dwVolume that is out of range is clamped by TAPI to the nearest value in range.

Return Value

Returns dwRequestID or an error number if an error occurs. The lResult actual parameter of the corresponding ASYNC_COMPLETION is zero if the function succeeds or it is an error number if an error occurs. The following table shows the return values for this method.

Value	Description
PHONEERR_INVALPHONEHANDLE	The handle to the phone is invalid.
PHONEERR_RESOURCEUNAVAIL	The resource is unavailable.
PHONEERR_INVALPHONESTATE	The phone state is invalid.

PHONEERR_INVALRINGMODE	The ring mode is invalid.
PHONEERR_OPERATIONUNAVAIL	The operation is unavailable.

Remarks

The service provider defines the actual audible ringing patterns corresponding to each of the phone's ring modes.
