Hi guys, first time using the mailing list, hope im not doing anything =
wrongt :)
ok ive got some questions about the ruby core
1. C-Methods: how is it possible to do a printf command for the =
delivered VALUE parameters?
Example
VALUE
rb_funcall(VALUE recv, ID mid, int n, ...)
{
...
}
/*
for example I would like to get the value of the variable recv printed =
on the command line using something like printf(recv);=20
reason for that is, that is just want to see what values any variable =
of the datatype VALUE has got
I know that c types can be "easily" printed, like the type ID : =
printf("%s", rb_id2name(nameOfVariableID))
*/
2. C-Method: how can I get to know the datatype of a VALUE variable?
Example
VALUE
rb_somemethod(VALUE somevalue, VALUE anothervalue)
{
char s =3D TYPE(somevalue); /* imagined code */
printf("%s",s); /* imagined code */
}
3. C-Method: how can I call a method which is defined somewhere by using =
C ?
Example
# Rubycode
class RubyClass
def x()
p "x"
end
end
/*C-code*/
void
rb_call_a_func()
{
/*imagined code*/
getClass("RubyClass").getMethod("x").execute();
} =20
Thanks for your help, and sorry if I posted it in the wrong "section"
