PHONESTATUS

This structure describes the current status of a phone device. The phoneGetStatus and TSPI_phoneGetStatus functions return this structure.

Members

• dwTotalSize**
  Total size, in bytes, allocated to this data structure.
• dwNeededSize
  Size, in bytes, for this data structure that is needed to hold all the returned information.
• dwUsedSize
  Size, in bytes, of the portion of this data structure that contains useful information.
• dwStatusFlags
  Set of status flags for this phone device. This member uses one of the PHONESTATUSFLAGS.
• dwNumOwners
  Number of application modules with owner privilege for the phone.
• dwNumMonitors
  Number of application modules with monitor privilege for the phone.
• dwRingMode
  Current ring mode of a phone device.
• dwRingVolume
  Current ring volume of a phone device. This is a value between 0x00000000 (silence) and 0x0000FFFF (maximum volume).
• dwHandsetHookSwitchMode
  Current hookswitch mode of the phone's handset. This member uses one of the PHONEHOOKSWITCHMODE.
• dwHandsetVolume
  Current speaker volume of the phone's handset device. This is a value between 0x00000000 (silence) and 0x0000FFFF (maximum volume).
• dwHandsetGain
  Current microphone gain of the phone's handset device. This is a value between 0x00000000 (silence) and 0x0000FFFF (maximum gain).
• dwSpeakerHookSwitchMode
  Current hookswitch mode of the phone's speakerphone. This member uses one of the PHONEHOOKSWITCHMODE constants.
• dwSpeakerVolume
  Current speaker volume of the phone's speaker device. This is a value between 0x00000000 (silence) and 0x0000FFFF (maximum volume).
• dwSpeakerGain
  Current microphone gain of the phone's speaker device. This is a value between 0x00000000 (silence) and 0x0000FFFF (maximum gain).
• dwHeadsetHookSwitchMode
  Current hookswitch mode of the phone's headset. This member uses one of the PHONEHOOKSWITCHMODE_ constants.
• dwHeadsetVolume
  Current speaker volume of the phone's headset device. This is a value between 0x00000000 (silence) and 0x0000FFFF (maximum volume).
• dwHeadsetGain
  Current microphone gain of the phone's headset device. This is a value between 0x00000000 (silence) and 0x0000FFFF (maximum gain).
• dwDisplaySize
  Size, in bytes, of the variably sized field containing the phone's current display information.
• dwDisplayOffset
  Offset, in bytes, from the beginning of this data structure.
• dwLampModesSize
  Size, in bytes, of the variably sized field containing the phone's current lamp modes.
• dwLampModesOffset
  Offset, in bytes, from the beginning of this data structure.
• dwOwnerNameSize
  Size, in bytes, of the variably sized field containing the name of the application that is the current owner of the phone device. The name is the application name provided by the application when it invoked with phoneInitializeEx. If no application name was supplied, the application's file name is used instead. If the phone currently has no owner, dwOwnerNameSize is zero.
• dwOwnerNameOffset
  Offset, in bytes, from the beginning of this data structure.
• dwDevSpecificSize
  The size, in bytes, of the variably sized device-specific field
• dwDevSpecificOffset
  Offset, in bytes, from the beginning of this data structure.
• dwPhoneFeatures
  These flags indicate which Telephony API functions can be invoked on the phone, considering the availability of the feature in the device capabilities, the current device state, and device ownership of the invoking application. A zero indicates the corresponding feature cannot be invoked by the application on the phone in its current state; a one indicates the feature can be invoked. This member uses one or more of the PHONEFEATURE.

Remarks

Device-specific extensions should use the DevSpecific (dwDevSpecificSize and dwDevSpecificOffset) variably sized area of this data structure.

The dwPhoneFeatures member is available only to applications that open the phone device with an API version of 2.0 or later.

Requirements

OS Versions: Windows CE 3.0 and later.
Header: Tapi.h.
