ping_iterator_get(3)						     liboping						      ping_iterator_get(3)

NAME

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

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.
