     NAME
          lh_stats, lh_node_stats, lh_node_usage_stats, lh_stats_bio,

     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
          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 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.
