       cpg_iteration_initialize - Initialize iterator for members of CPG


       #include <corosync/cpg.h>

       cs_error_t    cpg_iteration_initialize    (cpg_handle_t    handle,    cpg_iteration_type_t
       iteration_type,     const     struct     cpg_name      *group,      cpg_iteration_handle_t


       The cpg_iteration_initialize function is used to initialize iteration of CPG members.  The
       handle argument is connection  to  CPG  database  obtained  by  calling  cpg_initialize(3)
       function.  iteration_type is used for limit number of returned items and can be one of:

       CPG_ITERATION_NAME_ONLY - only name of used groups are returned

       CPG_ITERATION_ONE_GROUP - only members group with name group are returned

       CPG_ITERATION_ALL - all members are returned

       The  group parameter is used only with CPG_ITERATION_ONE_GROUP and it's name of group with
       members to iterate. For other iteration_type, this parameter must be NULL.

       cpg_iteration_initialize   is   used   only   for   initialize    context    for    future
       cpg_iteration_next(3)   calls   and  handle  needed  for  that  function  is  returned  in
       cpg_iteration_handle variable.  When  you  have  finished  iteration  over  objects,  call
       cpg_iteration_finalize(3) function to free up memory associated with iteration.


       This  call  returns  the  CS_OK  value  if  successful.  If  cpg_iteration_handle is NULL,
       CS_ERR_INVALID_PARAM error is returned. Same error  is  returned  when  iteration_type  is
       CPG_ITERATION_ONE_GROUP,  but  group is NULL, or when group is not NULL and iteration_type
       is not CPG_ITERATION_ONE_GROUP. If there is not enough memory for internal store of  data,
       CS_ERR_NO_MEMORY  is  returned.  CS_ERR_BAD_HANDLE can be returned, if handle is not valid
