pitem
Pointer to an HD_ITEM structure that contains information about the header item associated with the

Remarks
When a header control sends the HDN_BEGINTRACK, HDN_DIVIDERDBLCLICK,
HDN_ENDTRACK, HDN_ITEMCHANGED, HDN_ITEMCHANGING, HDN_ITEMCLICK, or HDN_TRACK
notification codes, it passes a pointer to an HD_NOTIFY structure as the lParam parameter of a WM_NOTIFY message.
