_ttof() for different locales

[ahmd]

Was just curious how does _ttof() behave for different locales?

Does it just stick with US standard to parse a floating point number or is it specific for a locale of a current user (for say, instead of 1.23 in US it may be expecting 1,23 for some European locales)?

Do you suggest us to make such a test for you?
What prevents you to test it yourself?

No, I don't. I just want to make sure that it behaves like I expect it to. Otherwise it'd be too expensive to fix it post-date.

After having done some digging around, I'm inclined to believe that it is much more safe to use _tstof_l() with a specific locale, for U.S. format, for instance, rather than leaving it up to chance. Here's a code example:

//Init locale (when app starts)
_locale_t localeUS;
localeUS = _create_locale(LC_ALL, "English_United States.1252");

...

//Then, for say, de-serializing from a data file
double f = _tstof_l(string, localeUS);

...
//And the clean-up when app quits
if(localeUS)
	_free_locale(localeUS);
