Expand description
@brief Iterates over all neighbor cache entries in the NIB
@pre (state != NULL) && (nce != NULL)
@param[in] iface Restrict iteration to entries on this interface. 0 for any interface. @param[in,out] state Iteration state of the neighbor cache. Must point to a NULL pointer to start iteration. @param[out] nce The next neighbor cache entry.
Usage example:
#include "net/gnrc/ipv6/nib/nc.h"
int main(void) {
void *state = NULL;
gnrc_ipv6_nib_nc_t nce;
puts("My neighbors:");
while (gnrc_ipv6_nib_nc_iter(0, &state, &nce)) {
gnrc_ipv6_nib_nc_print(&nce);
}
return 0;
}
@note The list may change during iteration.
@return true, if iteration can be continued. @return false, if @p nce is the last neighbor cache entry in the NIB.
