<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.

<p>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>
<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>
<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>

<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" title="Provides a thin abstraction layer over the underlying database client library.">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. </p>
