import a C++ function

import a C++ function

[Szymon Guz]

Hi,
how can I import from a dll such a function written in C:

static CRuntimeClass* PASCAL Load(CArchive& ar, UINT* pwSchemaNum);

the main problem I've got is with the "PASCAL" word.
And one thing more, how to declare the CArchive class, bacause writing
type CArchive;
doesn't help. The truth is that I don't have the type CArchive written 
in Ada yet and I only want to declare it, sth. like defining in C:
class CArchive;
