NAME

       isprint - test for a printable character

SYNOPSIS

       #include <ctype.h>

       int isprint(int c);

DESCRIPTION

       The  isprint()  function  shall  test  whether  c  is a character of class print in the program's current
       locale; see the Base Definitions volume of IEEE Std 1003.1-2001, Chapter 7, Locale.

       The c argument is an int, the value of which the application shall ensure is a character representable as
       an unsigned char or equal to the value of the macro EOF.  If  the  argument  has  any  other  value,  the
       behavior is undefined.

RETURN VALUE

       The isprint() function shall return non-zero if c is a printable character; otherwise, it shall return 0.

       listed in the SEE ALSO section should be used for character classification.

RATIONALE
