+*dosmap.c - Maps OS errors to errno values
+*
+*	Copyright (c) 1989-1993, Microsoft Corporation. All rights reserved.
+*
+*Purpose:
+*	_dosmaperr: Maps OS errors to errno values
+*
+*Revision History:
+*	06-06-89  PHG	Module created, based on asm version
+*	06-16-89  PHG	Changed name to _dosmaperr
+*	08-22-89  JCR	ERROR_INVALID_DRIVE (15) now maps to ENOENT not EXDEV
+*	03-07-90  GJF	Made calling type _CALLTYPE1, added #include
+*			<cruntime.h> and fixed copyright. Also, cleaned up the
+*			formatting a bit.
+*	09-27-90  GJF	New-style function declarator.
+*	12-04-90	SRW	 Changed to include <oscalls.h> instead of <doscalls.h>
+*	12-06-90  SRW	Added _CRUISER_ and _WIN32 conditionals.
+*	04-26-91  SRW	Added ERROR_LOCK_VIOLATION translation to EACCES
+*	08-15-91  GJF	Multi-thread support for Win32.
+*	03-31-92  GJF	Added more error codes (Win32 only) and removed OS/2
+*			specific nomenclature.
+*	07-29-92  GJF	Added ERROR_FILE_EXISTS to table for Win32. It gets
+*			mapped it to EEXIST.
+*	09-14-92  SRW	Added ERROR_BAD_PATHNAME table for Win32. It gets
+*			mapped it to ENOENT.
+*	10-02-92  GJF	Map ERROR_INVALID_PARAMETER to EINVAL (rather than
+*			EACCES). Added ERROR_NOT_LOCKED and mapped it to
+*			EACCES. Added ERROR_DIR_NOT_EMPTY and mapped it to
+*			ENOTEMPTY.
+*	02-16-93  GJF	Changed for new _getptd().
