.. \*(C` and \*(C' are quotes in nroff, nothing in troff, for use with C<>.
. ds C` "" . ds C' "" 'br\} . ds C` . ds C' 'br\}
Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "OPENSSL_LH_STATS 3ossl" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
OPENSSL_LH_stats, OPENSSL_LH_node_stats, OPENSSL_LH_node_usage_stats, OPENSSL_LH_stats_bio, OPENSSL_LH_node_stats_bio, OPENSSL_LH_node_usage_stats_bio - LHASH statistics Header "SYNOPSIS" .Vb 1 #include <openssl/lhash.h> .Ve

The following functions have been deprecated since OpenSSL 3.1, and can be hidden entirely by defining OPENSSL_API_COMPAT with a suitable version value, see openssl_user_macros\|(7):

.Vb 2 void OPENSSL_LH_node_stats(LHASH *table, FILE *out); void OPENSSL_LH_node_usage_stats(LHASH *table, FILE *out); \& void OPENSSL_LH_node_stats_bio(LHASH *table, BIO *out); void OPENSSL_LH_node_usage_stats_bio(LHASH *table, BIO *out); \& void OPENSSL_LH_stats(LHASH *table, FILE *out); void OPENSSL_LH_stats_bio(LHASH *table, BIO *out); .Ve

Header "DESCRIPTION" The LHASH structure records statistics about most aspects of accessing the hash table.

\fBOPENSSL_LH_stats() prints out statistics on the size of the hash table and how many entries are in it. For historical reasons, this function also outputs a number of additional statistics, but the tracking of these statistics is no longer supported and these statistics are always reported as zero.

\fBOPENSSL_LH_node_stats() prints the number of entries for each 'bucket' in the hash table.

\fBOPENSSL_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.

\fBOPENSSL_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 BIO.

These functions are deprecated and should no longer be used.

Header "RETURN VALUES" These functions do not return values. Header "NOTE" These calls should be made under a read lock. Refer to "NOTE" in OPENSSL_LH_COMPFUNC\|(3) for more details about the locks required when using the LHASH data structure. Header "SEE ALSO" \fBbio\|(7), OPENSSL_LH_COMPFUNC\|(3) Header "HISTORY" These functions were deprecated in version 3.1. Header "COPYRIGHT" Copyright 2000-2022 The OpenSSL Project Authors.
