/*************************************************************************
* SHSimpleIDListFromPath [SHELL32.162]
* _ILParsePathW [internal]
*
* Creates an ItemIDList from a path and returns it.
*
* PARAMS
* path [I] path to parse and convert into an ItemIDList
* lpFindFile [I] pointer to buffer to initialize the FileSystem
* Bind Data object with
* bBindCtx [I] indicates to create a BindContext and assign a
* FileSystem Bind Data object

* prgfInOut [I/O] requested attributes on input and actual
* attributes on return
*
* RETURNS
* NO_ERROR on success or an OLE error code
*
* NOTES
* If either lpFindFile is non-NULL or bBindCtx is TRUE, this function
* creates a BindContext object and assigns a FileSystem Bind Data object
* to it, passing the BindContext to IShellFolder_ParseDisplayName. Each
* IShellFolder uses that FileSystem Bind Data object of the BindContext
* to pass data about the current path element to the next object. This
* is used to avoid having to verify the current path element on disk, so
* that creating an ItemIDList from a non existing path still can work.
