1.8.6 Data conversion in define-com-method

All IDL definitions map onto FLI definitions, mirroring the mapping that midl.exe does for C/C++. However, IDL provides some additional type information that C/C++ lacks (for instance the string attribute), so there are some additional conversions that Lisp performs when it can. For a complete example of data conversion, see the file examples\com\manual\args\args-impl.lisp in the LispWorks installation.

1.8.6.1 FLI types

1.8.6.2 In parameters

1.8.6.3 Out parameters

1.8.6.4 In-out parameters
