char narrow( char_type c, char dfault ) const; |
Converts a current locale-specific character c to its standard equivalent. The result is converted from char_type to char if needed. If no conversion can be performed, the function returns dfault.
Effectively calls std::use_facet< std::ctype<char_type> >(getloc()).narrow(c, dfault);.
| c | - | character to convert |
| dfault | - | character to return if the conversion was unsuccessful |
Character converted to its standard equivalent and then to char. dfault is returned if the conversion fails.
| widens characters (public member function) |
|
invokes do_narrow (public member function of std::ctype) |

| narrows a wide character to a single-byte narrow character, if possible (function) |
