lh_stats(3)
NAME
  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 particular
  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 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.

  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.

HISTORY
  These functions are available in all versions of SSLeay and OpenSSL.	This
  reference page is derived from the SSLeay documentation.
