* SHELL32_BindToChild [Internal]

* PARAMS
* pidlRoot [I] The parent shell folder's absolute pidl.
* pathRoot [I] Absolute dos path of the parent shell folder.
* pidlComplete [I] PIDL of the child. Relative to pidlRoot.
* riid [I] GUID of the interface, which ppvOut shall be bound to.
* ppvOut [O] A reference to the child's interface (riid).
*
* NOTES
* pidlComplete has to contain at least one non empty SHITEMID.
* This function makes special assumptions on the shell namespace, which
* means you probably can't use it for your IShellFolder implementation.
