lineGetCurrentOperator

Send Feedback

Use the lineGetCurrentOperator function to retrieve the network operator on which the device is currently registered. This data is separate from the LINEOPERATORSTATUS structure for performance reasons.

LONG WINAPI lineGetCurrentOperator(
  HLINE hLine,
  LPLINEOPERATOR lpCurrentOperator
);

Parameters

  • hLine
    The line device handle. The line device handle must have been previously obtained by a call to lineOpen with the proper TAPI device ID specified and a device-specific extension version successfully negotiated with lineNegotiateExtVersion. For more information about lineNegotiateExtVersion and lineOpen, see the TAPI Functions API Reference topics on MSDN.
  • lpCurrentOperator
    Points to a LINEOPERATOR structure, which reports the state of the operator settings. Use the lineGetRegisterStatus function to determine the registration status of the device.

Return Values

Returns zero if the function completes successfully, or a negative error number if an error occurs. The following are possible return values:

LINEERR_RESOURCEUNAVAIL
LINEERR_INVALLINEHANDLE
LINEERR_STRUCTURETOOSMALL
LINEERR_INVALPOINTER
LINEERR_UNINITIALIZED
LINEERR_NOMEM
LINEERR_OPERATIONUNAVAIL
LINEERR_OPERATIONFAILED

Remarks

This function is synchronous. No LINE_REPLY message is sent and the application can use the contents of the parameter structures immediately after this function returns. Not implemented for CDMA.

**Note   **The lineGetCurrentOperator function does not return the short string for the current operator. The long string for the current operator is returned for display purposes only. For operator selection, use the numeric ID instead.

Pocket PC: Pocket PC 2002 and later.
Smartphone: Smartphone 2002 and later.
