Hi,
if I use rb\_str\_new2(something) to return a string value from within
a C function, do I have to free something after that or is something
used within the resulting ruby object?
regards

rb\_str\_new2(something) duplicate `something' otherwise it will not
possible to write
VALUE tt(VALUE obj)
{
return rb\_str\_new2("aa");
}

GC will clean it up for you after you’re finished with it (that is, when
nothing refers to it any longer).
