45 * The Shell Light-Weight Api dll provides a large number of utility functions
46 * which are commonly required by Win32 programs. Originally distributed with
47 * Internet Explorer as a free download, it became a core part of Windows when
48 * Internet Explorer was 'integrated' into the O/S with the release of Win98.
50 * All functions exported by ordinal are undocumented by MS. The vast majority
51 * of these are wrappers for Unicode functions that may not exist on early 16
52 * bit platforms. The remainder perform various small tasks and presumably were
53 * added to facilitate code reuse amongst the MS developers.
