s_v_l
synopsis: OP s_v_l(OP vectorobject)
description:
selects the length of an VECTOR object. There is first a
check whether it is really an VECTOR object. There is also a
check whether the length is a not negative number.
return:
s_v_l gives the length part of the VECTOR object, this is
an INTEGER object, it is not a copy of the length part.
s_v_li gives the INTvalue of the length part. It is equivalent
to s_i_i(s_v_l()). If an error occured s_v_l returns NULL
and s_v_li() returns ERROR.
macro:
there are macro versions which do no checks, they are called
S_V_L and S_V_LI
