std::basic_ios::imbue(3)       C++ Standard Libary	std::basic_ios::imbue(3)

NAME
     std::basic_ios::imbue - std::basic_ios::imbue

Synopsis
	std::locale imbue( const std::locale& loc );

	Replaces  the current locale. Effectively calls ios_base::imbue(loc) and
     if there is
	an associated stream buffer (rdbuf() != 0), then  calls  rdbuf()->pubim-
     bue(loc).

Parameters
	loc - the new locale

Return value
	The previous locale, as returned by ios_base::imbue(loc).

Exceptions
	May throw implementation-defined exceptions.

Example
     // Run this code

      #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';
      }

Output:
      Current locale: en_US.UTF8
      Global locale : C
