lh_stats(3)                                        OpenSSL                                       lh_stats(3)



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 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.

RETURN VALUES
       These functions do not return values.
