std::iswxdigit(3) C++ Standard Libary std::iswxdigit(3) NAME std::iswxdigit - std::iswxdigit Synopsis Defined in header <cwctype> int iswxdigit( wint_t ch ); Checks if the given wide character corresponds (if narrowed) to a hexadecimal numeric character, i.e. one of 0123456789abcdefABCDEF. If the value of ch is neither representable as a wchar_t nor equal to the value of the macro WEOF, the behavior is undefined. Parameters ch - wide character Return value Non-zero value if the wide character is a hexadecimal numeric char- acter, zero otherwise. Notes std::iswdigit and std::iswxdigit are the only standard wide charac- ter classification functions that are not affected by the currently installed C locale.
