| isc_result_t | isc_stats_create (isc_mem_t *mctx, isc_stats_t **statsp, int ncounters) |

| int | isc_stats_ncounters (isc_stats_t *stats) |
| Returns the number of counters contained in stats. | |
| void | isc_stats_increment (isc_stats_t *stats, isc_statscounter_t counter) |
| Increment the counter-th counter of stats. | |
| void | isc_stats_decrement (isc_stats_t *stats, isc_statscounter_t counter) |
| Decrement the counter-th counter of stats. | |
| void | isc_stats_dump (isc_stats_t *stats, isc_stats_dumper_t dump_fn, void *arg, unsigned int options) |
| Dump the current statistics counters in a specified way. For each counter in stats, dump_fn is called with its current value and the given argument arg. By default counters that have a value of 0 is skipped; if options has the ISC_STATSDUMP_VERBOSE flag, even such counters are dumped. | |
| void | isc_stats_set (isc_stats_t *stats, isc_uint64_t val, isc_statscounter_t counter) |
| Set the given counter to the specfied value. | |
