KNET_HANDLE_GET_STATS(3)

NAME
knet_handle_get_stats - Get statistics for compression & crypto.

SYNOPSIS
#include <libknet.h>

int knet_handle_get_stats(
    knet_handle_t               knet_h,
    struct knet_handle_stats   *stats,
    size_t                      struct_size
);

DESCRIPTION

knet_handle_get_stats

knet_h - pointer to knet_handle_t

knet_handle_stats pointer to a knet_handle_stats structure

struct_size size of knet_handle_stats structure to allow for backwards compatibility. libknet will only copy this much data into the stats structure so that older callers will not get overflowed if new fields are added.

STRUCTURES

Detailed stats for this knet handle as returned by knet_handle_get_stats()
