Pike_sp-- vs. pop_stack() (Re: Accessing variables in a class object from within a CMOD?)

One more question:

When doing the following:

Pike_sp++; object_index_no_free2(Pike_sp-1, portal, 0, MK_STRING_SVALUE("_total"));

What am I supposed to do to cleanup after using the returned svalue?

Pike_sp--; or pop_stack();

?

And, on a related note, what if I do:

Pike_sp++; object_index_no_free2(Pike_sp-1, portal, 0, MK_STRING_SVALUE("_total")); ... some processing ... object_set_index2(portal,0, MK_STRING_SVALUE("_total"), Pike_sp-1);

What do I need at this point, Pike_sp-- or pop_stack() ?

In the above examples the values of _total could have been arrays or ints or strings; I presume the answers are the same regardless of the datatype.
