OPENSSL_LH_STATS(3)                 OpenSSL                OPENSSL_LH_STATS(3)
NAME
       OPENSSL_LH_stats, OPENSSL_LH_node_stats, OPENSSL_LH_node_usage_stats,
       OPENSSL_LH_stats_bio, OPENSSL_LH_node_stats_bio,
       OPENSSL_LH_node_usage_stats_bio - LHASH statistics
SYNOPSIS
        #include <openssl/lhash.h>
        void OPENSSL_LH_stats(LHASH *table, FILE *out);
        void OPENSSL_LH_node_stats(LHASH *table, FILE *out);
        void OPENSSL_LH_node_usage_stats(LHASH *table, FILE *out);
        void OPENSSL_LH_stats_bio(LHASH *table, BIO *out);
        void OPENSSL_LH_node_stats_bio(LHASH *table, BIO *out);
        void OPENSSL_LH_node_usage_stats_bio(LHASH *table, BIO *out);
DESCRIPTION
       The LHASH structure records statistics about most aspects of accessing
       the hash table.
       OPENSSL_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.
       OPENSSL_LH_node_stats() prints the number of entries for each 'bucket'
       in the hash table.
       OPENSSL_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.
       OPENSSL_LH_stats_bio(), OPENSSL_LH_node_stats_bio() and
       OPENSSL_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.
NOTE
       These calls should be made under a read lock. Refer to "NOTE" in
       OPENSSL_LH_COMPFUNC(3) for more details about the locks required when
       using the LHASH data structure.
