lh_stats, lh_node_stats, lh_node_usage_stats, lh_stats_bio, |

lh_node_stats_bio, lh_node_usage_stats_bio - LHASH statistics |

=head1 SYNOPSIS |
|
|

#include <openssl/lhash.h> |
|
|

void lh_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); |

=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. |
|
|
|
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 B<BIO>. |
