std::basic_ios<CharT,Traits>::imbue
Min standard notice:
Replaces the current locale. Effectively calls ios_base::imbue(loc) and if there is an associated stream buffer (rdbuf() != 0), then calls rdbuf()->pubimbue(loc).
# Declarations
std::locale imbue( const std::locale& loc );
# Parameters
loc: the new locale
# Return value
The previous locale, as returned by ios_base::imbue(loc).
# Example
#include <iostream>
#include <locale>
#include <sstream>
int main()
{
std::istringstream iss;
iss.imbue(std::locale("en_US.UTF8"));
std::cout << "Current locale: " << iss.getloc().name() << '\n';
iss.imbue(std::locale());
std::cout << "Global locale : " << iss.getloc().name() << '\n';
}
