char narrow( char_type c,char dfault)const; | ||
Converts a current locale-specific characterc to its standard equivalent. The result is converted fromchar_type tochar if needed. If no conversion can be performed, the function returnsdfault.
Effectively callsstd::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 tochar.dfault is returned if the conversion fails.
