NAME

cpg_membership_get - Returns a list of members of a CPG group

SYNOPSIS

#include <corosync/cpg.h>

int cpg_membership_get(cpg_handle_t handle, struct cpg_name
*groupName, struct cpg_address *member_list, int
*member_list_entries);

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.
