/***
|
|
*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)
