There is no generic api routine to do that. In principle, the following
(not so good) way may be used:
LPX *from, *to;
. . .
memcpy(((char *)to) + offsetof(LPX, msg_lev),
((char *)from) + offsetof(LPX, msg_lev),
sizeof(LPX) - offsetof(LPX, msg_lev));
However I can't imagine in which cases this operation would be
necessary, because changing the default value of a control parameter is
(as a rule) specific for a particular problem instance.
