14.2 Include Files

The include files used in Example 14-1 are the standard ones, except for the few needed to perform system calls to get the user’s home directory, current Rubout key, etc. The <X11/Xresource.h> file is necessary to use the resource manager.

Example 14-1. basecalc — include files

#include <X11/Xlib.h>
#include <X11/Xutil.h>
#include <X11/Xresource.h>
#include <X11/cursorfont.h>

#include <stdio.h>

#ifdef SysV
#include <termio.h>
#else
#include <sgtty.h>
#include <sys/ttychars.h>
#endif SysV

#include <ctype.h>
#include <pwd.h>

/* Global declarations file for this application */
#include "basecalc.h"

The constant definitions and global variables declared or defined in ./basecalc.h are shown above the routines in which they are used in the basecalc example program. You can take a look at the entire include file in Appendix D.
