afaik, there is C ABI, that defines how to pass and return parameters of simple types, it's common for all compilers supporting so-called "cdecl" on any architecture (x86, x86-64, ppc, so on). C ABI doesn't define how to pass structures, so we can't generate universal assembler code for this example - it depends on what compiler we want to interact to moreover, even for pointers-to-structures, there is no definitive layout due to packing problem OTOH, we could try to use gcc agreements -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
