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. -- - Alfred Perlstein - Research Engineering Development Inc. - email: bright@mu.org cell: 408-480-4684
