NAME

ping_iterator_get, ping_iterator_next - Iterate over all hosts of a liboping object

CONTENTS

SYNOPSIS



  #include <oping.h>

  pingobj_iter_t *ping_iterator_get (pingobj_t *obj);
  pingobj_iter_t *ping_iterator_next (pingobj_iter_t *iter)



DESCRIPTION

These two functions can be used to iterate over all hosts associated with a liboping object. You can use these methods as follows:



  pingobj_iter_t *iter;

  for (iter = ping_iterator_get (obj);
       iter != NULL;
       iter = ping_iterator_next (iter))
  {
    ...;
  }



To get usable information from an iterator object (which is also an opaque data type, just like the liboping object itself) use ping_iterator_get_info(3) and ping_iterator_get_context(3).

RETURN VALUE

The ping_iterator_get returns an iterator for obj or NULL if no host is associated with obj.

The ping_iterator_next returns an iterator for the host following iter or NULL if the last host has been reached.
