phoneClose

  • Article

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 If the function succeeds, the handle is no longer valid.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.
PHONEERR_UNINITIALIZED The parameter is uninitialized.

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.
Link Library: Coredll.lib.
