Hi all,
Sorry to bother you.
I want to use NOX to collect the flow stats. So I try to use
ofp_flow_stats_request and flow_stats_in event to do it.
When I receive the event of flow_stats_in, I print the stats like bytes to
screen. But there is a problem that it shows
wrong value in screen. I read the code of openvswitch, it use a strange format
to store bytes of flow entry counter
which name is ovs_32aligned_u64 in include/openvswitch/type.h.
typedef struct {
#ifdef WORDS_BIGENDIAN
uint32_t hi, lo;
#else
uint32_t lo, hi;
#endif
} ovs_32aligned_u64;
I use printf("%lld", flow.bytes) to output this format, but it is wrong in
screen. And if I change lld to PRIx64, it is wrong too.
So I want to know how to output this format to decimal in screen?
Thanks very much.
