protected virtual member function
<locale>
std::ctype::do_scan_is
const char_type* do_scan_is (mask m, const char_type* low, const char_type* high) const;
Return first character in category [virtual]
Virtual protected member function called by ctype::scan_is to locate characters of specific categories.
Polymorphic derived classes can overwrite the behavior of this function.
See ctype::scan_is for its default behavior in ctype.
The char specialization of ctype (ctype<char>) does not have this member, as its member scan_is returns its results directly.
