NAME
       cpg_iteration_next - Return next item in iteration of CPG

SYNOPSIS
       #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.

RETURN VALUE
       This call returns the CS_OK value if successful. If there are no more items to iterate, CS_NO_SECTION error code is returned.
