| <P>An example of when you would want to imbue a new locale on a stream might be the case where a file has a header that requires a different code conversion facet. The following code imbues the JIS to UNICODE conversion facet from <A HREF="40.html">Chapter 40</A> onto a stream, reads a single line, then imbues the default locale to continue processing the file:</P> |
| |
| <UL><PRE> |
| std::wstring header; |
| std::wstring body; |
| typedef std::basic_ifstream<wchar_t,JIS_char_traits> JIS_ifstream; |
| JIS_fstream in("special.txt"); |
| UnicodeJISConversion<wchar_t,char,JISstate_t> cvtfac; |
| std::locale cvtloc(std::locale(),&cvtfac); |
| in.rdbuf()->pubimbue(cvtloc); |
| std::getline(in,header); |
| in.rdbuf()->pubimbue(std::locale()); |
| in >> body; |
| </PRE></UL> |
