POPDC.H

The public symbol file NTKRPAMP.PDB for the original release of Windows 10 tells that the kernel is built with the POPDC.H header at

d:\th\minkernel\po\pdc\inc

and draws from it the following type definitions:

Line Number Type
75 struct _POP_TRIGGER_WAIT
83 struct _POP_ACTION_TRIGGER
93 unnamed struct for Battery in _POP_ACTION_TRIGGER
97 unnamed struct for Button in _POP_ACTION_TRIGGER

The header POPDC.H is not known in any Device Driver Kit (DDK) or Windows Driver Kit (WDK).
