Synopsis:
    #include <ctype.h>
    int isspace( int c );

Description:
    The isspace function tests for the following white-space characters:

    ' '
        space

    '\f'
        form feed

    '\n'
        new-line or linefeed

    '\r'
        carriage return

    '\t'
        horizontal tab

    '\v'

Returns:
    The isspace function returns a non-zero character when the argument is
    one of the indicated white-space characters; 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 space character\n",
                chars[i],
                ( isspace( chars[i] ) ) ? "" : "not " );
        }
      }

    produces the following:

    Char A is not a space character
    Char     is a space character
    Char   is a space character
    Char } is not a space character
