I can tell you the easiest way to answer this precise question, but a
more general answer would involve asking more about what you want to
do within the interpeter.  The easiest way to create a structure that
looks like the above is to use:

    char buf[256];
    sprintf (buf, "struct{c=%d, d=struct{a=%d, b=%d}};", 
                  second.c, first.a, first.b);
    (void) SLang_load_string (buf);

The use of SLang_load_string has the effect of pushing the structure
onto the slang stack.  While this will accomplish the stated goal, I
am not sure if this is really what you want.
