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


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

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.

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

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.
