| Please observe the following notes when making changes to the source
 | |
| tree.
 | |
| 
 | |
| The directory h contains header files used internally in the zephyr
 | |
| source tree.  The directory h/zephyr contains header files containing
 | |
| declarations for the Zephyr API.  h/zephyr/zephyr_err.h is generated
 | |
| from lib/zephyr/zephyr_err.et when lib/zephyr is built.
 | |
| h/zephyr/zephyr.h is generated by configure, as is h/config.h.  Those
 | |
| header files live in the build tree.  All other header files in h live
 | |
| in the source tree.
 | |
| 
 | |
| h/config.h is generated by configure and contains the results of
 | |
| configure tests as well as definitions for the installation
 | |
| configuration directory and data directory.  h/sysdep.h uses
 | |
| h/config.h to include various header files or make various external
 | |
| declarations which many programs might be interested in.  h/internal.h
 | |
| contains declarations internal to the "Zephyr system proper," which
 | |
| includes the Zephyr library, the server, the hostmanager, and (for
 | |
| now) zstat.
 | |
| 
 | |
| h/zephyr/zephyr.h is a public header file; that is, it is installed
 | |
| with the Zephyr system.  As such, this header file may need to work
 | |
| with compilers other than the compiler used to build the Zephyr system
 | |
| itself.  Thus, we use __STDC__ (both in h/sysdep.h and in zephyr.h) to
 | |
| guess whether the compiler will handle const, prototypes, and stdarg.
 | |
| This is unfortunately not as reliable as using autoconf features like
 | |
| AC_C_CONST.
