lineGetAddressID

  • Article

This function returns the address identifier associated with an address in a different format on the specified line.

LONG WINAPI lineGetAddressID(
  HLINE hLine,
  LPDWORD lpdwAddressID,
  DWORD dwAddressMode,
  LPCWSTR lpsAddress,
  DWORD dwSize 
);

Parameters

  • hLine
    Handle to the open line device.
  • lpdwAddressID
    Pointer to a DWORD-sized memory location where the address identifier is returned. An address identifier is permanently associated with an address; the identifier remains constant across operating system upgrades.
  • dwAddressMode
    Address mode of the address contained in lpsAddress. This parameter uses one and only one of the LINEADDRESSMODE constants. You must specify LINEADDRESSMODE_DIALABLEADDR.
  • lpsAddress
    Pointer to a data structure holding the address assigned to the specified line device. The format of the address is determined by dwAddressMode. Because the only valid value is LINEADDRESSMODE_DIALABLEADDR, lpsAddress uses the common dialable number format and is null-terminated.
  • dwSize
    Size of the address contained in lpsAddress.

Return Values

Returns zero if the request succeeds or a negative error number if an error occurs. The following table shows the return values for this function.

Value Description
LINEERR_INVALLINEHANDLE The handle to the open line device is invalid.
LINEERR_OPERATIONUNAVAIL The operation is unavailable.
LINEERR_INVALADDRESSMODE The address mode is invalid.
LINEERR_OPERATIONFAILED The operation failed.
LINEERR_INVALPOINTER The pointer is invalid.
LINEERR_RESOURCEUNAVAIL The resources are unavailable.
LINEERR_INVALADDRESS The address is invalid.
LINEERR_UNINITIALIZED A parameter is unitialized.
LINEERR_NOMEM Not enough memory is available.

Remarks

The lineGetAddressID function is used to map a phone number (address) assigned to a line device back to its dwAddressID in the range zero to the number of addresses minus one returned in the line's device capabilities. The lineMakeCall function allows the application to make a call by specifying a line handle and an address on the line. The address can be specified as a dwAddressID, as a phone number, or as a device-specific name or identifier. Using a phone number can be practical in environments where a single line is assigned multiple addresses.

Note   This function is for TAPI version 2.0 and later.

Note   LINEADDRESSMODE_ADDRESSID may not be used with lineGetAddressID.
