public member function
<ios> <iostream>

std::ios::imbue

locale imbue (const locale& loc);
Imbue locale
Associates loc to both the stream and its associated stream buffer (if any) as the new locale object to be used with locale-sensitive operations.

This function calls its inherited homonym ios_base::imbue(loc) and, if the stream is associated with a stream buffer, it also calls rdbuf()->pubimbue(loc).

All callback functions registered with member register_callback are called by ios_base::imbue.

Parameters

loc
locale object to be imbued as the new locale for the stream.

Return value

The locale object associated with the stream before the call.

// imbue example
#include <iostream>     // std::cout
#include <locale>       // std::locale

int main()
{
  std::locale mylocale("");   // get global locale
  std::cout.imbue(mylocale);  // imbue global locale
  std::cout << 3.14159 << '\n';
  return 0;
}

This code writes a floating point number using the global locale given by the environment. For example, in a system configured with a Spanish locale as default, this could write the number using a comma decimal separator:
3,14159


Data races

Modifies the stream object.
Concurrent access to the same stream object may cause data races.

Exception safety

Basic guarantee: if an exception is thrown, the stream is in a valid state.
