/***
|
|
*initnum.c - contains _init_numeric
|
|
*
|
|
* Copyright (c) 1991-1993, Microsoft Corporation. All rights reserved.
|
|
*
|
|
*Purpose:
|
|
* Contains the locale-category initialization function: _init_numeric().
|
|
*
|
|
* 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 Change interface to _getlocaleinfo again.
|
|
* 02-08-93 CFW Added _lconv_static_*.
|
|
* 02-17-93 CFW Removed debugging print statement.
|
|
* 03-17-93 CFW C locale thousands sep is "", not ",".
|
|
* 05-20-93 GJF Include windows.h, not individual win*.h files
|
|
* 06-11-93 CFW Now inithelp takes void *.
