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