Copies the object referred by the
l-value
lval_src into the object referred
by the
l-value
lval_tgt. This function is especially
useful in a situation, when the both source and target are
unions
and the source object contains
analytic
data items. The
copy_object
function then copies the content of the source object with preserving the
analytic
data items. A similar operation can be performed with the
assignment
operator, in that case, however, only the instant state of the object is copied. Therefore,
analytic data items are converted to their respective
free
types.
