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

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

    The iswgraph function is similar to isgraph except that it accepts a
    wide-character argument.

Returns:
    The isgraph function returns non-zero when the argument is a printable
    character (except a space).  The iswgraph function returns a non-zero
    value when the argument is a printable wide character (except a
    wide-character space).  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],
                ( isgraph( chars[i] ) ) ? "" : "not " );
        }
      }

    produces the following:

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