phoneClose (Windows CE 5.0)
This function closes the specified open phone device.
LONG WINAPI phoneClose(HPHONE hPhone);
Parameters
- hPhone
Handle to the open phone device to be closed. If the function succeeds, the handle is no longer valid.
Return Values
Returns zero if the request succeeds or a negative error number if an error occurs. The following table shows the return values for this function.
| Value | Description |
|---|---|
| PHONEERR_INVALPHONEHANDLE | The handle to the open phone device is invalid. |
| PHONEERR_NOMEM | Not enough memory is available. |
| PHONEERR_OPERATIONFAILED | The operation failed. |
| PHONEERR_RESOURCEUNAVAIL | The resources are unavailable. |
| PHONEERR_OPERATIONUNAVAIL | The operation is unavailable. |

Remarks
After the open phone device has been successfully closed, the implementation sends a PHONE_CLOSE message to the application. These messages can also be sent unsolicited as a result of the phone device being reclaimed somehow. An application should therefore be prepared to handle these unsolicited close messages. At the time the phone device is closed, any outstanding asynchronous replies are suppressed.
Note This function is for TAPI version 2.0 and later.
Requirements
OS Versions: Windows CE 3.0 and later.
Header: Tapi.h.
