| DESCRIPTION |
| <<isxdigit>> is a macro which classifies ASCII integer values by table |
| lookup. It is a predicate returning non-zero for hexadecimal digits, |
| and <<0>> for other characters. It is defined only when |
| <<isascii>>(<[c]>) is true or <[c]> is EOF. |
| and <<0>> for other characters. It is defined only if <[c]> is |
| representable as an unsigned char or if <[c]> is EOF. |
| You can use a compiled subroutine instead of the macro definition by |
| undefining the macro using `<<#undef isxdigit>>'. |
