cpg_iteration_next - Return next item in iteration of CPG

#include <corosync/cpg.h>
cs_error_t cpg_iteration_next (cpg_iteration_handle_t handle, struct cpg_iteration_description_t *description);
DESCRIPTION
The cpg_iter_next function is used to get next value in iteration. The handle argument is iterator handle obtained by cpg_iteration_inital-
ize(3) function. description is pointer to structure with following definition:
struct cpg_iteration_description_t {
struct cpg_name group;
uint32_t nodeid;
uint32_t pid;
};
where group is name of group, nodeid is ID of connected node and pid is pid of connected process. If iteration was initialized with
CPG_ITERATION_NAME_ONLY iteration type, both nodeid and pid are 0.
