phoneClose  8OJWUJ 

The phoneClose function closes the specified open phone device.

LONG phoneClose(

    HPHONE hPhone

 

   );

 

 

Parameters

hPhone

A handle to the open phone device to be closed. If the function is successful, the handle is no longer valid.

 

Return Values

Returns zero if the request is successful or a negative error number if an error has occurred. Possible return values are:

PHONEERR_INVALPHONEHANDLE, PHONEERR_NOMEM, PHONEERR_OPERATIONFAILED, PHONEERR_RESOURCEUNAVAIL, PHONEERR_OPERATIONUNAVAIL, PHONEERR_UNINITIALIZED.

Remarks

After the open phone device has been successfully closed, the implementation sends a PHONE_CLOSE message to the application. Note that 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.
