37  * SHLWAPI {SHLWAPI}

39  * The Shell Light-Weight API dll provides a large number of utility functions
40  * which are commonly required by Win32 programs. Originally distributed with
41  * Internet Explorer as a free download, it became a core part of Windows when
42  * Internet Explorer was 'integrated' into the O/S with the release of Win98.
43  *
44  * All functions exported by ordinal are undocumented by MS. The vast majority
45  * of these are wrappers for Unicode functions that may not exist on early 16
46  * bit platforms. The remainder perform various small tasks and presumably were
47  * added to facilitate code reuse amongst the MS developers.
