NAME
       lh_stats, lh_node_stats, lh_node_usage_stats,
       lh_stats_bio, lh_node_stats_bio, lh_node_usage_stats_bio
       - LHASH statistics

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 rea-
       sons of implementing what looked like a nice algorithm
       rather than for a particular 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 aver-
       age 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.

RETURN VALUES
       These functions do not return values.

       and OpenSSL.
