+<a name="sqlitestatusmemoryused"></a>
+ <dt>SQLITE_STATUS_MEMORY_USED</dt>
+<dd>This parameter is the current amount of memory checked out
+using <a href="../c3ref/free.html">sqlite3_malloc()</a>, either directly or indirectly. The
+figure includes calls made to <a href="../c3ref/free.html">sqlite3_malloc()</a> by the application
+and internal memory usage by the SQLite library. Auxiliary page-cache
+memory controlled by <a href="../c3ref/c_config_covering_index_scan.html#sqliteconfigpagecache">SQLITE_CONFIG_PAGECACHE</a> is not included in
+this parameter. The amount returned is the sum of the allocation
+sizes as reported by the xSize method in <a href="../c3ref/mem_methods.html">sqlite3_mem_methods</a>.</dd></p>
+
+<p><a name="sqlitestatusmallocsize"></a>
+ <dt>SQLITE_STATUS_MALLOC_SIZE</dt>
+<dd>This parameter records the largest memory allocation request
+handed to <a href="../c3ref/free.html">sqlite3_malloc()</a> or <a href="../c3ref/free.html">sqlite3_realloc()</a> (or their
+internal equivalents). Only the value returned in the
+*pHighwater parameter to <a href="../c3ref/status.html">sqlite3_status()</a> is of interest.
+The value written into the *pCurrent parameter is undefined.</dd></p>
+
+<p><a name="sqlitestatusmalloccount"></a>
+ <dt>SQLITE_STATUS_MALLOC_COUNT</dt>
+<dd>This parameter records the number of separate memory allocations
+currently checked out.</dd></p>
+
+<p><a name="sqlitestatuspagecacheused"></a>
+ <dt>SQLITE_STATUS_PAGECACHE_USED</dt>
+<dd>This parameter returns the number of pages used out of the
+<a href="../malloc.html#pagecache">pagecache memory allocator</a> that was configured using
+<a href="../c3ref/c_config_covering_index_scan.html#sqliteconfigpagecache">SQLITE_CONFIG_PAGECACHE</a>. The
+value returned is in pages, not in bytes.</dd></p>
+
+<p><a name="sqlitestatuspagecacheoverflow"></a>
+
+<dt>SQLITE_STATUS_PAGECACHE_OVERFLOW</dt>
+<dd>This parameter returns the number of bytes of page cache
+allocation which could not be satisfied by the <a href="../c3ref/c_config_covering_index_scan.html#sqliteconfigpagecache">SQLITE_CONFIG_PAGECACHE</a>
+buffer and where forced to overflow to <a href="../c3ref/free.html">sqlite3_malloc()</a>. The
+returned value includes allocations that overflowed because they
+where too large (they were larger than the "sz" parameter to
+<a href="../c3ref/c_config_covering_index_scan.html#sqliteconfigpagecache">SQLITE_CONFIG_PAGECACHE</a>) and allocations that overflowed because
+no space was left in the page cache.</dd></p>
+
+<p><a name="sqlitestatuspagecachesize"></a>
+ <dt>SQLITE_STATUS_PAGECACHE_SIZE</dt>
+<dd>This parameter records the largest memory allocation request
+handed to the <a href="../malloc.html#pagecache">pagecache memory allocator</a>. Only the value returned in the
+*pHighwater parameter to <a href="../c3ref/status.html">sqlite3_status()</a> is of interest.
+The value written into the *pCurrent parameter is undefined.</dd></p>

+<p><a name="sqlitestatusscratchused"></a>
+ <dt>SQLITE_STATUS_SCRATCH_USED</dt>
+<dd>No longer used.</dd></p>

+<dd>No longer used.</dd></p>
+
+<p><a name="sqlitestatusparserstack"></a>
+ <dt>SQLITE_STATUS_PARSER_STACK</dt>
+<dd>The *pHighwater parameter records the deepest parser stack.
+The *pCurrent value is undefined. The *pHighwater value is only
+meaningful if SQLite is compiled with <a href="../compile.html#yytrackmaxstackdepth">YYTRACKMAXSTACKDEPTH</a>.</dd>
