William,

I have not seen the #pragma once; in the CCS 3.3 documentation.
Perhaps I just missed it. Though I have browsed the documentation on pragma
statements.

An alternative, that at least works with C++ is to use the simple "#pragma
once" http://en.wikipedia.org/wiki/Pragma_once

It may be a non-standard directive, but It seems to work in the Code
Composer Studio tools (3.1.23) that I'm using, as well as the current
version of MS Visual Studio.

Asif,

Each header file (must) have a wrapper that stops the file from being loaded
more than once for any one compilation.

From the error messages, I see that the tmwtypes.h header file does not have
that wrapper.
Notes:
1) the name used is not critical, but; it must be unique.
2) use '_' not '.' in the defined name
3) standard practice is to capitalize the defined name
4) standard practice is to use the header file name for the defined name
5) good programing practice is to put a comment at the end of the header file
after the #endif
6) good programing practice is to put a comment on the #endif to indicate which
'#if' it is associated to
7) good programing practice is to put a descriptive header at the beginning of
the header file, immediately before (or after) the '#define' statement

The wrapper is written as follows:
===========================================================/* ****************************** *\
* descriptive comments
\* ****************************** */
#ifndef TMWTYPES_H
#define TMWTYPES_H

.. contents of header file here ..

#endif /* TMWTYPES_H */
/* End of header file: tmwtypes.h */
===========================================================R. Williams
