For compiling, fsync() is defined in <unistd.h>, in the include directory,
so use "-I/POSIXC60/include" in your compile.  If you are writing C source
code, use "#include <unistd.h> at the top of your source where you include
header files.

For linking, fsync() is in libposix60.a in the lib directory; you can use it
as is right away! :-)  Libposix60.a does have a dependency of also including
the socket and svipc libraries - use
"-L/POSIXC60/lib -lposix60 -lsocket -lsvipc" in your link.

Finally, if you want all the details, directory posix.1_notavail/fsync
contains:
   - fsync.c - the C source of fsync()
   - fsynct.c - a test program which which calls fsync()
   - Makefile which compiles and links the programs
Entering "make clean" and then "make", you will see the commands executed,
showing all the options for compiling and linking I mentioned above.

2 test programs are built from the same test source.  The first, fsynct, is
linked without the Porting Wrappers to demonstrate the it does not run
because fsync() today is missing from MPE.  The second, fsynctw, is linked
with libposix60.a and executes as desired.  Our future plans call for adding
fsync() and all the other Porting Wrappers to MPE.
