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_initalize(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.
