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. It is a legacy of Eric Young who wrote the library for
the purpose of implementing a useful algorithm rather than for a par‐
ticular software product.
The lh_stats() function 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.
The lh_node_stats() function prints the number of entries for each
bucket in the hash table.
The lh_node_usage_stats() function 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 num‐
ber 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.
The lh_stats_bio(), lh_node_stats_bio(), and lh_node_usage_stats_bio()
functions are the same, except that the output goes to a BIO.
RETURN VALUES
These functions do not return values.
