      Definido no cabeçalho <locale.h>
      char* setlocale( int category, const char* locale);
      A função setlocale instala a localidade do sistema especificado ou a sua parte como a localidade C novo. As modificações continuam em vigor e influencia a execução de todos os sensíveis à localidade funções de biblioteca C até a próxima chamada para setlocale. Se locale é um ponteiro nulo, setlocale consulta a localidade C atual, sem modificá-lo.
      Original:
      The setlocale function installs the specified system locale or its portion as the new C locale. The modifications remain in effect and influences the execution of all locale-sensitive C library functions until the next call to setlocale. If locale is a null pointer, setlocale queries the current C locale without modifying it.
