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.
