std::basic_ios<CharT,Traits>::narrow - std::basic_ios<CharT,Traits>::narrow


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

Return value

Character converted to its standard equivalent and then to char. dfault is returned if the conversion fails.
