; DESCRIPTION:
; The file contains the structures and equates used by the Unicode
; translation and parsing code.
;
; MODIFICATION HISTORY:
;----------------------------------------------------------------------------
;--------------------------------------------------------------------------
; Flags returned by UniToBCS, BCSToUni, UniToBCSPath, MapUniToBCS
; MapBCSToUni. The flags indicate whether a mapping from UNICODE
; to BCS, or BCS to UNICODE have lost information. This occurs
; whenever a char cannot be mapped.
;--------------------------------------------------------------------------
MAP_FLAG_LOSS equ 00001h

;--------------------------------------------------------------------------
; Equates used to identify special character types
;--------------------------------------------------------------------------

OEM_INDEX equ 1 ; Equate defining the entry in the translation
; table ptr array (utbPtrTable) to be used as
; the default OEM codepage when auto-generating
; short names.
MAX_CHAR_SETS equ 2 ; Maximum # of entries in utbPtrTable array.
;--------------------------------------------------------------------------
; Auto-generation flags returned from CreateBasis()
;--------------------------------------------------------------------------
UFLG_LOSS equ 00000010h
