[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.
