inittime.c

C语言库函数的原型,有用的拿去

/***
*inittime.c - contains __init_time
*
*       Copyright (c) Microsoft Corporation. All rights reserved.
*
*Purpose:
*       Contains the locale-category initialization function: __init_time().
*
*       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 ***

*Purpose:
*       In non-C locales, read the localized time/date strings into

*       the new one is fully established.
