radcli_avp_iter_next3
Return the current attribute and advance.
Usage
#include <radcli/>
const radcli_avp * radcli_avp_iter_next(
radcli_avp_iter *it
);
Overview
Parameters
it-
an iterator from radcli_avp_list_iter().
Structures
Iterator over a radcli_avp_list.
A plain value: construct with radcli_avp_list_iter(), advance with radcli_avp_iter_next(). No allocation, safe to copy, safe to run several independent iterators over the same list concurrently (as long as nothing mutates the list while any of them are in use see radcli_avp_list_st's locking note in lib/avp.c). Fields are an implementation detail; do not access them directly. Deliberately not opaque via an incomplete type: a two-pointer cursor belongs on the caller's stack at zero cost, the way any ccan/list or kernel list cursor does, not behind a heap allocation.
Usage: radcli_avp_iterit=radcli_avp_list_iter(list);
constradcli_avp*a;
while((a=radcli_avp_iter_next(&it))!=NULL){
}
struct radcli_avp_iter {
const radcli_avp_list *list;
const radcli_avp *cur;
};
Return value
the current attribute, or NULL once the list is exhausted every subsequent call on the same it also returns NULL; it does not restart.
