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>>'. |
