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.
HISTORY
These functions are available in all versions of SSLeay and
OpenSSL.
