Files like dh.pod, etc., mostly duplicated the API-specific pod files. Removed the duplicated content; that often mean the whole file could be removed. Some of the content about internals got moved into README files in the source tree. Some content (e.g., err.pod) got moved into other pod pages. Annotate generic pages, remove dup NAME Reviewed-by: Richard Levitte <levitte@openssl.org>

=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>.
