FUNCTION

        <<isprint>>, <<isgraph>>---printable character predicates

INDEX

        isprint

INDEX

        isgraph

ANSI_SYNOPSIS

        #include <ctype.h>

        int isprint(int <[c]>);

        int isgraph(int <[c]>);

TRAD_SYNOPSIS

        #include <ctype.h>

        int isprint(<[c]>);

        int isgraph(<[c]>);

DESCRIPTION

<<isprint>> is a macro which classifies ASCII integer values by table

lookup.  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.

You can use a compiled subroutine instead of the macro definition by

undefining either macro using `<<#undef isprint>>' or `<<#undef isgraph>>'.

RETURNS

<<isprint>> returns non-zero if <[c]> is a printing character,

(<<0x20>>--<<0x7E>>).

<<isgraph>> behaves identically to <<isprint>>, except that the space

character (<<0x20>>) is excluded.

PORTABILITY

<<isprint>> and <<isgraph>> are ANSI C.

No supporting OS subroutines are required.
