<hr><a name="_details"></a><h2>Detailed Description</h2>
Provides a thin abstraction layer over the underlying database client library.
<p>
This class does as little as possible to adapt between its public interface and the interface required by the underlying C API. That is, in fact, its only mission. The high-level interfaces indended for use by MySQL++ users are in <a class="el" href="classmysqlpp_1_1Connection.html">Connection</a>, <a class="el" href="classmysqlpp_1_1Query.html">Query</a>, Result, and ResUse, all of which delegate the actual database communication to an object of this type, created by <a class="el" href="classmysqlpp_1_1Connection.html">Connection</a>. If you really need access to the low-level database driver, get it via <a class="el" href="classmysqlpp_1_1Connection.html#0d118df40a7bd4bb63e7286b221f7680">Connection::driver()</a>; don't create <a class="el" href="classmysqlpp_1_1DBDriver.html">DBDriver</a> objects directly.<p>
Currently this is a concrete class for wrapping the MySQL C API. In the future, it may be turned into an abstract base class, with subclasses for different database server types.

This method has three basic operation modes:<p>
<ul>
<li>Pass just a pointer to a C++ string containing the original data to escape, plus act as receptacle for escaped version</li><li>Pass a pointer to a C++ string to receive escaped string plus a pointer to a C string to be escaped</li><li>Pass nonzero for all parameters, taking original to be a pointer to an array of char with given length; does not treat null characters as special</li></ul>
<p>
There's a degenerate fourth mode, where ps is zero: simply returns 0, because there is nowhere to store the result.<p>
Note that if original is 0, we always ignore the length parameter even if it is nonzero. Length always comes from ps->length() in this case.<p>
ps is a pointer because if it were a reference, the other overload would be impossible to call: the compiler would complain that the two overloads are ambiguous because std::string has a char* conversion ctor. A nice bonus is that pointer syntax makes it clearer that the first parameter is an "out" parameter.<p>

The MySQL++ user manual's <a href="../userman/threads.html">chapter on threads</a> details two major strategies for dealing with connections in the face of threads. If you take the simpler path, creating one <a class="el" href="classmysqlpp_1_1DBDriver.html">DBDriver</a> object per thread, it is never necessary to call this function; the underlying C API will call it for you when you establish the first database server connection from that thread. If you use a more complex connection management strategy where it's possible for one thread to establish a connection that another thread uses, you must call this from each thread that can use the database before it creates any MySQL++ objects. If you use a DBDriverPool object, this applies; DBDriverPool isn't smart enough to call this for you, and the MySQL C API won't do it, either.
