/***
*initmon.c - contains __init_monetary
*
* Copyright (c) 1991-2001, Microsoft Corporation. All rights reserved.
*
*Purpose:
* Contains the locale-category initialization function: __init_monetary().
*
* Each initialization function sets up locale-specific information
* for their category, for use by functions which are affected by
* their locale category.
*
* *** For internal use by setlocale() only ***
*
*Revision History:
* 12-08-91 ETC Created.
* 12-20-91 ETC Updated to use new NLSAPI GetLocaleInfo.
* 12-18-92 CFW Ported to Cuda tree, changed _CALLTYPE4 to _CRTAPI3.
* 12-29-92 CFW Updated to use new _getlocaleinfo wrapper function.
* 01-25-93 KRS Changed _getlocaleinfo interface again.
* 02-08-93 CFW Added _lconv_static_*.
* 02-17-93 CFW Removed debugging print statement.
* 04-06-93 SKS Replace _CRTAPI* with __cdecl
* 04-20-93 CFW Check return val.
* 05-20-93 GJF Include windows.h, not individual win*.h files
* 05-24-93 CFW Clean up file (brief is evil).
* 06-11-93 CFW Now inithelp takes void *.
* 09-15-93 CFW Use ANSI conformant "__" names.
* 09-22-93 GJF Merged NT SDK and Cuda versions.
* 04-15-94 GJF Removed declarations of __lconv and __lconv_c (both
* are declared in setlocal.h). Made definition of
* __lconv_intl conditional on DLL_FOR_WIN32S.
* 08-02-94 CFW Change "3;0" to "\3" for grouping as per ANSI.
* 09-06-94 CFW Remove _INTL switch.
* 01-10-95 CFW Debug CRT allocs.
* 06-30-98 GJF Changed to support new multithread scheme - old lconv
* structs must be kept around until all affected threads
* have updated or terminated.
* 12-08-98 GJF Fixed logic in __free_lconv_mon.
* 03-15-99 GJF Added __lconv_mon_refcount
* 04-24-99 PML Added __lconv_intl_refcount
* 10-12-00 PML Don't call fix_grouping if error detected (vs7#169596)

*int __init_monetary() - initialization for LC_MONETARY locale category.
*
*Purpose:
* In non-C locales, read the localized monetary strings into
* __lconv_intl, and also copy the numeric strings from __lconv into
* __lconv_intl. Set __lconv to point to __lconv_intl. The old
* __lconv_intl is not freed until the new one is fully established.
*
* In the C locale, the monetary fields in lconv are filled with
* contain C locale values. Any allocated __lconv_intl fields are freed.
*
* At startup, __lconv points to a static lconv structure containing
* C locale strings. This structure is never used again if
* __init_monetary is called.
*
*Entry:
* None.
*
*Exit:
* 0 success
* 1 fail
*
*Exceptions:
