=head1 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);

=head1 DESCRIPTION
|
|
|
|
The B<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.
|
|
|
|
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 B<BIO>.
