confchg callbacks you will get will be from the cpg_join()
function containing your process. The argument <i>handle</i>
is used to reference the cpg instantiation. The argument
<i>groupName</i> will return the name of the group The
argument <i>member_list</i> will return the list of
processors in the current membership. The argument
<i>member_list_entries</i> should be set with the size of
member_list and will return the size of the member_list
after return from the function.</p>
