         ldap_enable_cache(LDAP *ld, long timeout, long maxmem);
         void ldap_disable_cache(LDAP *ld);
         void ldap_destroy_cache(LDAP *ld);
         void ldap_flush_cache(LDAP *ld);
         void ldap_uncache_entry(LDAP *ld, char *dn);
         void ldap_uncache_request(LDAP *ld, int msgid);
         void ldap_set_cache_options(LDAP *ld, unsigned long opts);
         These functions are used to control the behavior  of  client
         caching  of  ldap_search(3LDAP),  cldap_search_s(3LDAP), and
         ldap_compare(3LDAP) operations.  By default,  the  cache  is
         disabled  and  no  caching  is done.  Enabling the cache can
         greatly improve performance  and  reduce  network  bandwidth
         when a client DUA makes repeated requests.
         ldap_enable_cache() should be called to turn on local  cach-
         ing  or  to  change  cache  parameters  (lifetime  of cached
         requests and memory used). The ld parameter  should  be  the
         result of a successful call to ldap_open(3LDAP). The timeout
         is specified in seconds, and is used to decide how  long  to
         keep  cached requests.  The maxmem value is in bytes, and is
         used to set an upper bound on how memory the cache will use.
         You  can  specify 0 for maxmem to restrict the cache size by
         the timeout  only.   The  first  call  to  ldap_enable_cache
         creates  the cache; subsequent calls re-enable the cache and
         set the timeout and memory values.
         ldap_disable_cache() temporarily disables use of  the  cache
         (new  requests  are  not cached and the cache is not checked
         when returning results).  It does not delete the cache  con-
         ldap_destroy_cache()  turns  off  caching   and   completely
         removes the cache from memory.
         ldap_flush_cache() deletes the cache contents, but does  not
         effect it in any other way.
         ldap_uncache_entry() removes all requests that  make  refer-
         ence to the distinguished name dn from the cache.  It should
         be used, for example, after doing an ldap_modify(3LDAP) call
         involving dn.
         ldap_uncache_request() removes the request indicated by  the
         LDAP request id msgid from the cache.
         ldap_set_cache_options() is used to change caching behavior.
         The current supported options are LDAP_CACHE_OPT_CACHENOERRS
         to suppress caching of any requests that result in an error,
         and  LDAP_CACHE_OPT_CACHEALLERRS  to  enable  caching of all
         requests.  The default behavior is  to  not  cache  requests
         that  result  in  errors, except that request that result in
         the error LDAP_SIZELIMIT_EXCEEDED are cached.
         ldap_enable_cache() returns  0 upon success, and  -1  if  it
         is  unable  to  allocate space for the cache.  All the other
         calls are declared as void and return nothing.
