As stated (and slightly modified) in the WM_SIZING documentation:
'The edge of the window that is being sized [read: moved].'
The contents translate to the same WMSZ_* enumeration as WM_SIZING. It allows you to get and set the 'detection point' for overlapping another window for example (dragging left? wParam checks left and bottom, dragging right? wParam checks top and right, or any other sort of combo like that).
The WMSZ_* enumeration is treated as flags, e.g, a wParam value of '9' is possible, translating back to WMSZ_LEFT and WMSZ_BOTTOMRIGHT. This way it is more returning an 'area' than a 'location'. Not sure if this is any different with WM_SIZING.
Oh, also, this was observed under Windows 7.
