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

Syntax

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.
  • 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 Value

Returns a positive request identifier if the function is completed asynchronously, or 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.

This is a privileged function.
