    I'm doing some work that requires that I have a sysctl structure
    be passed around, but inside that structure are several pointers I
    may need to dereference.

    Basically:

    struct mysysctldata {
       .... (data here)
       void *moredata;
       size_t morelen;
    };

    What is the proper way of sysctl'ing IN the data from moredata?

    I need to make a copy of the sysctl req, but... I'm not sure what
    to initialize the 'lock' member to.

    Any hints would be appeciated.
