//
|

// Arguments: [pwszInput] - the string containing the catalog URL
|
||
|
|
// [xpCatalog] - pointer where catalog is returned if any
|
||
|
|
// [xpMachine] - pointer where machine is returned if any
|
||
|
|
//
|
||
|
|
// Notes: If there is no machine name specified, the default machine
|
||
|
|
// name ( "." ) is used.
