SYNOPSIS    [Toc]    [Back]

       #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    [Toc]    [Back]

       The  LHASH structure records statistics about most aspects
       of accessing the hash table.  It is a legacy of Eric Young
       who  wrote  the  library for the purpose of implementing a
       useful algorithm rather than  for  a  particular  software
       product.

       The  lh_stats() function 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.

       The lh_node_stats() function prints the number of  entries
       for each bucket in the hash table.

       The lh_node_usage_stats() function 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.

       The      lh_stats_bio(),      lh_node_stats_bio(),     and
       lh_node_usage_stats_bio() functions are the  same,  except
       that the output goes to a BIO.
