Use the lineGetCurrentOperatorfunction to retrieve the network operator on which the device is currently registered. This data is separate from the LINEOPERATORSTATUSstructure for performance reasons.

Syntax 

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 lineOpenwith the proper TAPI device ID specified and a device-specific extension version successfully negotiated with lineNegotiateExtVersion.

lpCurrentOperator

Points to a LINEOPERATORstructure, which reports the state of the operator settings. Use the lineGetRegisterStatusfunction to determine the registration status of the device.

Return Value

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 lineGetCurrentOperatorfunction 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.
