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);.
[edit] Parameters
c
-
character to convert
dfault
-
character to return if the conversion was unsuccessful
[edit] Return value
Character converted to its standard equivalent and then to char. dfault is returned if the conversion fails.
