Re: Can someone give me an example of the SNAME type ?

[Rivka Miller]

Can someone explain me the essential parts of this function,
specifically, with some examples of SNAME ? How should the SNAME look
like ?

     DEFUN ("or", For, Sor, 0, UNEVALLED, 0,
       doc: /* Eval args until one of them yields non-nil, then return
that
     value. The remaining args are not evalled at all.
     If all args return nil, return nil.
     usage: (or CONDITIONS ...)  */)
       (args)
          Lisp_Object args;
     {
       register Lisp_Object val = Qnil;
       struct gcpro gcpro1;

       GCPRO1 (args);

       while (CONSP (args))
         {
           val = Feval (XCAR (args));
           if (!NILP (val))
        break;
           args = XCDR (args);
         }

       UNGCPRO;
       return val;
     }
