Synopsis:
    #include <ctype.h>
    int isprint( int c );
    #include <wchar.h>
    int iswprint( wint_t c );

Description:
    The isprint function tests for any printable character including space
    (' ').  The  isgraph function is similar, except that the space
    character is excluded from the character set being tested.

    The iswprint function is similar to isprint except that it accepts a
    wide-character argument.

Returns:
    The isprint function returns a non-zero value when the argument is a
    printable character.  The iswprint function returns a non-zero value
    when the argument is a printable wide character.  Otherwise, zero is
    returned.

Example:
    #include <stdio.h>
    #include <ctype.h>

    char chars[] = {
        'A',
        0x09,
        ' ',
        0x7d
    };

    #define SIZE sizeof( chars ) / sizeof( char )

    void main()
      {
        int   i;

        for( i = 0; i < SIZE; i++ ) {
          printf( "Char %c is %sa printable character\n",
                chars[i],
                ( isprint( chars[i] ) ) ? "" : "not " );
        }
      }

    produces the following:

    Char A is a printable character
    Char     is not a printable character
    Char   is a printable character
    Char } is a printable character
