Exemplo
The following example demonstrated retrieval of messages: on a typical GNU/Linux system it reads from /usr/share/locale/de/LC_MESSAGES/sed.mo
#include <iostream>
#include <locale>
int main()
{
std::locale loc("de_DE.utf8");
std::cout.imbue(loc);
auto& facet = std::use_facet<std::messages<char>>(loc);
auto cat = facet.open("sed", loc);
if(cat < 0 )
std::cout << "Could not open german \"sed\" message catalog\n";
else
std::cout << "\"No match\" in German: "
<< facet.get(cat, 0, 0, "No match") << '\n'
<< "\"Memory exhausted\" in German: "
<< facet.get(cat, 0, 0, "Memory exhausted") << '\n';
facet.close(cat);
}
Saída:
"No match" in German: Keine Übereinstimmung
"Memory exhausted" in German: Speicher erschöpft
