[ros-dev] Autogenerating compiler specific .def files

[Alex Ionescu]

The @16 is not an ordinal, it's the number of arguments on the stack in
bytes.

The .rbuild should define 4 things:

1) Function convention (@fastcall at x, _stdcall at x or _cdecl)
2) Bytes on stack (only relevant for stdcall and fastcall)
3) Ordinal, optional
4) Forward/alias, optional
