// This file defines C and C++ replacements for scanf to parse a string in a
// locale-independent way. This is useful when parsing input data that comes
// not from user, but from some kind of a fixed protocol with predefined locale
// settings.
// Just use these functions as drop-in replacements of sscanf();
//
// Note1: if the input string contains any dot characters other than decimal
// separators, the results of parsing will be screwed: in Windows the
// implementation replaces all dots with the current decimal separator to parse
// using current locale.
// Note2: current implementation only supports parsing floating point numbers -
// no code for monetary values, dates, digit grouping etc.
// The limitation is because of MinGW's lack of per-thread locales support.
