/***
*initmon.c - contains _init_monetary
*
* Copyright (c) 1991-1993, 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.
* 05-20-93 GJF Include windows.h, not individual win*.h files
* 06-11-93 CFW Now inithelp takes void *.

*Purpose:

* 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.

* None.
