[Numpy-discussion] Another CXX question

This is probably a stupid coding error, but the following code generates
the error:

C:\Program Files\Microsoft Visual
Studio\MyProjects\Xrawdatafile\Xrawdatafile.cpp(32) : error C2065:
'FromAPI' : undeclared identifier

I've marked the line in the listing that causes the error.  It occurs in
the function that creates a new datafile_type object to return to the
interpreter.   Right now the datafile_type object is very simple, and has
but one method that prints a hardcoded string.  I'm using CXX-4.?? with
Visual C++ 6.0 and SP3.  I'm going to download SP4 tonight and see if that
helps, but any hints would be appreciated.  I haven't been doing C++ for
very long, so I'm probably mising something obvious.
