lineRegister

  • Article

Use the lineRegister function to register a device with a particular network operator.

LONG WINAPI lineRegister(
  HLINE hLine,
  DWORD dwRegisterMode,
  LPCTSTR lpszOperator,
  DWORD dwOperatorFormat
);

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 in the Windows CE SDK.

  • dwRegisterMode
    Identifies the mode for registration. Possible values are listed in the following table.

    Value Description
    LINEREGMODE_AUTOMATIC Automatically register with available operator.
    LINEREGMODE_MANUAL Explicitly register with a particular operator.
    LINEREGMODE_MANAUTO If manual registration fails, register automatically.

  • lpszOperator
    A string identifying the operator to register with. This parameter is ignored and optional if dwRegisterMode is LINEREGMODE_AUTOMATIC.

  • dwOperatorFormat
    Identifies the format of lpszOperator. This parameter is ignored and optional if dwRegisterMode is LINEREGMODE_AUTOMATIC. Possible values are listed in the following table.

    Value Description
    LINEOPFORMAT_NONE The lpszOperator field is unused.
    LINEOPFORMAT_ALPHASHORT Short text description.
    LINEOPFORMAT_ALPHALONG Long text description.
    LINEOPFORMAT_NUMERIC Numeric description.

Return Values

The lineRegister function returns a positive request identifier if the function is completed asynchronously and returns a negative error number if an error occurs. The dwParam2 parameter of the corresponding LINE_REPLY message is zero if the function succeeds or it is a negative error number if an error occurs. For more detail, see TAPI Synchronous/Asynchronous Model on Microsoft MSDN Online. The following are possible return values:

LINEERR_INVALLINEHANDLE
LINEERR_NOMEM
LINEERR_OPERATIONUNAVAIL
LINEERR_OPERATIONFAILED
LINEERR_RESOURCEUNAVAIL
LINEERR_INVALPOINTER
LINEERR_INVALPARAM
LINEERR_UNINITIALIZED

Remarks

When explicitly registering with a particular operator, the user should assume that the operator name is case-sensitive. Not implemented for CDMA.
