It is a predicate returning non-zero for printable characters, and 0 for other character arguments. -It is defined only when <<isascii>>(<[c]>) is true or <[c]> is EOF. +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 either macro using `<<#undef isprint>>' or `<<#undef isgraph>>'. |
