s_v_i
synopsis: OP s_v_i(OP vectorobject; INT index)
description:
selects the ith entry of an VECTOR object. There is first a
check whether it is really an VECTOR object. Then there is a check
whether index is a value inside the length.
As the VECTOR object is indexed by INT-numbers there is a
(theoretical) limit on the size of a VECTOR object, namely
there a maximal 2^31 elements.
return:
s_v_i gives the ith entry of the VECTOR object. In the case
of an error it returns NULL.
macro:
there is a macro version which does no checks, it
is called
S_V_I
