lineGetAddressID (Windows CE 5.0)
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.
