Struct in julia to C structs

Hello, julia structs is the same as C structs or not? i.e.:

struct Test
    x::Int
    y::Int 
end

will this be the same as this?

struct {
    int x;
    inx y;
}

No, use Cint instead.

i.e.:

struct Test
    x::Cint
    y::Cint
end

for me the main thing is that no additional fields are added to the struct after compilation.

Yeah, they have the same data layout, read it in the documentation
