<h2 class="first-section-title"><a name="429"></a><a name="ch04lev1sec3"></a>Keep It Simple...Stupid!</h2><p class="first-para">My goal in this chapter is to help you learn how to implement your own manual memory management code. I could have very easily gotten sidetracked with optimization, and my code would have quickly become very hard to read (if not impossible). If you want to see what I mean, go look at the <span class="fixed">malloc.c</span> code for the Gnu Compiler Collection. It should keep you occupied for a couple of hours, or maybe a day or two.</p>
<p class="para">Hence, I had to strike a balance between performance and comprehension. I have decided, in the interest of keeping the learning threshold low, that I would keep my source code <i class="emphasis">as simple as possible</i>. I will not try to impress you with syntactic acrobatics. Instead, I intend to show you the basic idea so that you can "get it" without seven hours of frustrating rereading. Having perused several <span class="fixed">malloc()</span> implementations myself, I know how demoralizing it can be to have to decipher optimized code.</p>
<a name="430"></a><a name="IDX-212"></a>
<p class="last-para">I also make the assumption that this chapter's code will be executing in a <i class="emphasis">single-threaded</i> environment. I know that some members of the reading audience may be gasping at my negligence. Again, I want to focus on memory management without being distracted by complicated synchronization issues. Once you have a working knowledge under your belt, you can add all the amenities. I will leave it as an exercise to the reader to make everything thread safe.</p>
