; If we have an invalid buffer pointer, we must return 0, not -1
; for 3.0 compatibility.  This is because some apps call these functions
; with bogus pointers at EOF, in which case DOS ignores the pointer and count.
; The P_HFILE parameter checking just warns about bogus values, which is
; later caught by DOS and returned as a -1 error.

; BUGBUG
; For Win95, the k16 Reg* APIs get only the weakest validation.
; This is because they were added without _any_ validation,
; and validation is being added after the final beta.
; The purpose of this weak validation is to touch each pointer
; param if non-zero. We need to do this because the real work of
; the APIs is done at ring0, where we cannot fault in the segment.
;
; Stronger validation should be implemented for the next release.
