lh_stats, lh_node_stats, lh_node_usage_stats, lh_stats_bio,
lh_node_stats_bio, lh_node_usage_stats_bio - LHASH statis-
tics
SYNOPSIS
#include <openssl/lhash.h>
void lh_stats(LHASH *table, FILE *out);
void lh_node_stats(LHASH *table, FILE *out);
void lh_node_usage_stats(LHASH *table, FILE *out);
void lh_stats_bio(LHASH *table, BIO *out);
void lh_node_stats_bio(LHASH *table, BIO *out);
void lh_node_usage_stats_bio(LHASH *table, BIO *out);
DESCRIPTION
The LHASH structure records statistics about most aspects of
accessing the hash table. This is mostly a legacy of Eric
Young writing this library for the reasons of implementing
what looked like a nice algorithm rather than for a particu-
lar software product.
lh_stats() prints out statistics on the size of the hash
table, how many entries are in it, and the number and result
of calls to the routines in this library.
lh_node_stats() prints the number of entries for each
'bucket' in the hash table.
lh_node_usage_stats() prints out a short summary of the
state of the hash table. It prints the 'load' and the
'actual load'. The load is the average number of data items
per 'bucket' in the hash table. The 'actual load' is the
average number of items per 'bucket', but only for buckets
which contain entries. So the 'actual load' is the average
number of searches that will need to find an item in the
hash table, while the 'load' is the average number that will
be done to record a miss.
lh_stats_bio(), lh_node_stats_bio() and
lh_node_usage_stats_bio() are the same as the above, except
that the output goes to a BIO.
