/***
*xtow.c - convert integers/longs to wide char string
*
* Copyright (c) 1993-2001, Microsoft Corporation. All rights reserved.
*
*Purpose:
* The module has code to convert integers/longs to wide char strings.
*
*Revision History:
* 09-10-93 CFW Module created, based on ASCII version.
* 02-07-94 CFW POSIXify.
* 01-19-96 BWT Add __int64 versions.
* 05-13-96 BWT Fix _NTSUBSET_ version
* 08-21-98 GJF Bryan's _NTSUBSET_ version is the correct
* implementation.

/***
*wchar_t *_itow, *_ltow, *_ultow(val, buf, radix) - convert binary int to wide
* char string
*
*Purpose:
* Converts an int to a wide character string.
*
*Entry:
* val - number to be converted (int, long or unsigned long)
* int radix - base to convert into
* wchar_t *buf - ptr to buffer to place result
*
*Exit:
* calls ASCII version to convert, converts ASCII to wide char into buf
* returns a pointer to this buffer
*
*Exceptions:
