This document describes the <span>C++</span> API for DB, version 4.8. It is intended to describe the DB API, including all classes, methods, and functions. As such, this document is intended for <span>C++</span> developers who are actively writing or maintaining applications that make use of DB databases. </p> <h2><a id="conventions"></a>Conventions Used in this Book</h2> <p> The following typographical conventions are used within in this manual: </p> <p> Class names are represented in <code class="classname">monospaced font</code>, as are <code class="methodname">method names</code>. For example: <span>"<code class="methodname">Db::open()</code> is a <code class="classname">Db</code> class method."</span> </p> <p> Variable or non-literal text is presented in <span class="emphasis"><em>italics</em></span>. For example: "Go to your <span class="emphasis"><em>DB_INSTALL</em></span> directory." </p> <p> Program examples are displayed in a <code class="classname">monospaced font</code> on a shaded background. For example: </p> <pre class="programlisting">typedef struct vendor { char name[MAXFIELD]; // Vendor name char street[MAXFIELD]; // Street name and number char city[MAXFIELD]; // City char state[3]; // Two-digit US state code char zipcode[6]; // US zipcode char phone_number[13]; // Vendor phone number } VENDOR; </pre> <div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"> <h3 class="title">Note</h3> <p> Finally, notes of interest are represented using a note block such as this. </p> </div> <h2><a id="moreinfo"></a>For More Information</h2> <p> Beyond this manual, you may also find the following sources of information useful when building a DB application: </p> <div class="itemizedlist"> <ul type="disc"> <li> <p> <a class="ulink" href="http://www.oracle.com/technology/documentation/berkeley-db/db/gsg/CXX/index.html" target="_top"> Getting Started with Berkeley DB for C++ </a> </p> </li> <li> <p> <a class="ulink" href="http://www.oracle.com/technology/documentation/berkeley-db/db/gsg_txn/CXX/index.html" target="_top"> Getting Started with Transaction Processing for C++ </a> </p> </li> <li> <p> <a class="ulink" href="http://www.oracle.com/technology/documentation/berkeley-db/db/gsg_db_rep/CXX/index.html" target="_top"> Berkeley DB Getting Started with Replicated Applications for C++ </a> </p> </li> <li> <p> <a class="ulink" href="http://www.oracle.com/technology/documentation/berkeley-db/db/api_reference/C/frame_main.html" target="_top"> Berkeley DB C API </a> </p> </li> <li> <p> <a class="ulink" href="http://www.oracle.com/technology/documentation/berkeley-db/db/api_reference/STL/frame_main.html" target="_top"> Berkeley DB STL API </a> </p> </li> <li> <p> <a class="ulink" href="http://www.oracle.com/technology/documentation/berkeley-db/db/api_reference/TCL/frame_main.html" target="_top"> Berkeley DB TCL API </a> </p> </li> <li> <p> <a class="ulink" href="http://www.oracle.com/technology/documentation/berkeley-db/db/programmer_reference/index.html" target="_top"> Berkeley DB Programmer's Reference Guide </a> </p> </li> </ul> </div> </div> <div class="navfooter"> <hr /> <table width="100%" summary="Navigation footer"> <tr> <td width="40%" align="left"><a accesskey="p" href="index.html">Prev</a> </td> <td width="20%" align="center"> </td> <td width="40%" align="right"> <a accesskey="n" href="introduction.html">Next</a></td> </tr> <tr> <td width="40%" align="left" valign="top">Berkeley DB C++ API Reference </td> <td width="20%" align="center"> <a accesskey="h" href="index.html">Home</a> </td> <td width="40%" align="right" valign="top"> Chapter 1.
