37 // from a DLL simpler. All files within this DLL are compiled with the COMPILE_CAMITK_API
38 // flag defined on the command line. this symbol should not be defined on any project
39 // that uses this DLL. This way any other project whose source files include this file see
40 // CAMITK_API functions as being imported from a DLL, wheras this DLL sees symbols
41 // defined with this macro as being exported.

61 // nothrow attribute.
62 // I did not find the throw attribute. It seems that msvc is therefore ignoring the
63 // specification of the type of the exception.
64 // The compiler therefore issues a warning.
65 // The following line is to avoid this particular warning.
66 // The best would be to ask msvc not only to take the exception into account, but also
67 // its type. Anyway, I did not find how to do that anywhere, and I am not sure this is
68 // possible...
