As for HPCON_INTERNAL,

typedef struct _HPCON_INTERNAL
{
  HANDLE hWritePipe;
  HANDLE hConDrvReference;
  HANDLE hConHostProcess;
} HPCON_INTERNAL;

hWritePipe:
This is for sending window size change message to pseudo console
(conhost.exe process).

hConDrvRererence:
I am not sure what this is for.

hConHostProcess:
Process handle of conhost.exe process.

None of them seems able to be used for that purpose.
I do not come up with other implementation so far.

Let me consider a while.
