DESCRIPTION
The cpg_membership_get function is used to determine the current processes in the configuration. You probably will not need to call this function much as one of the first confchg callbacks you will get will be from the cpg_join() function containing your process. The argument handle is used to reference the cpg instantiation. The argument groupName will return the name of the group The argument member_list will return the list of processors in the current membership. The argument member_list_entries should be set with the size of member_list and will return the size of the member_list after return from the function.ERRORS
The errors are undocumented.SEE ALSO
