Shouldn't that be *_Seg16?  I found the following in OS2DEF.H in the
\WATCOM\h\os21x directory:

typedef VOID   * _Seg16  PVOID16;

However, when using:

typedef PVOID16 HSEM16;
typedef HSEM16 * _Seg16 PHSEM16;
typedef const char * _Seg16 PCSZ16;

and linking with \WATCOM\lib386\os2\os2286.lib, and running the executable,
I got SYS3175 errors.  My assumption, of course, is that I was misusing
something.  So I loaded in the debugger.  I got a task exception fault
BEFORE I hit the 'execute line' button.  

Changing to

typedef void _far16 * HSEM16;
typedef HSEM16 _far16 * PHSEM16;
typedef const char _far16 * PCSZ16;

doesn't seem to help any.  :-(

And, yes, the functions *are* surrounded by 'extern "C" {'... :-)
