<p>The <a href="../../api_c/db_close.html">DB-&gt;close</a> method is the standard interface for closing the database.
20
 
By default, <a href="../../api_c/db_close.html">DB-&gt;close</a> also flushes all modified records from the
21
 
database cache to disk.
22
 
<p>There is one flag that you can set to customize <a href="../../api_c/db_close.html">DB-&gt;close</a>:
23
 
<p><dl compact>
24
 
<p><dt><a href="../../api_c/db_close.html#DB_NOSYNC">DB_NOSYNC</a><dd>Do not flush cached information to disk.
25
 
</dl>
26
 
<b>It is important to understand that flushing cached information
27
 
to disk only minimizes the window of opportunity for corrupted data, it
28
 
does not eliminate the possibility.</b>
29
 
<p>While unlikely, it is possible for database corruption to happen if a
30
 
system or application crash occurs while writing data to the database. To
31
 
ensure that database corruption never occurs, applications must either:
32
 
<p><ul type=disc>
33
 
<li>Use transactions and logging with automatic recovery.
34
 
<li>Use logging and application-specific recovery.
35
 
<li>Edit a copy of the database, and, once all applications
36
 
using the database have successfully called <a href="../../api_c/db_close.html">DB-&gt;close</a>, use
37
 
system operations (for example, the POSIX rename system call) to
38
 
atomically replace the original database with the updated copy.
