   <p><i>We just moved.</i> Those three little words should strike terror into the heart of anyone who owns more than a sleeping bag and a toothbrush. Our last move was the usual zoo&mdash;and then some. Because the distance from the old house to the new was only five miles, we used cars to move everything smaller than a washing machine. We have a sizable household&mdash;cats, dogs, kids, com, you name it&mdash;so the moving process took a number of car trips. A <i>large</i> number&mdash;33, to be exact. I personally spent about 15 hours just driving back and forth between the two houses. The move took days to complete.</p>

   <p>The application we&rsquo;re going to examine searches a file for a specified string. We&rsquo;ll develop a program that will search the file specified on the command line for a string (also specified on the comline), then report whether the string was found or not. (Because the searched-for string is obtained via <b>argv</b>, it can&rsquo;t contain any whitespace characters.)</p>

   <p>Well, it might be instructive to consider how we would search if our search involved only one buffer, already resident in memory. In other words, suppose we don&rsquo;t have to bother with file handling at all, and further suppose that we don&rsquo;t have to deal with searching through multiple blocks. After all, that&rsquo;s a good description of the all-important inner loop of our searching program, where the program will spend virtually all of its time (aside from the unavoidable disk access overhead).</p>

   <p>The easiest approach would be to use a C/C<small>++</small> library function. The closest match to what we need is <b>strstr()</b>, which searches one string for the first occurrence of a second string. However, while <b>strstr()</b> would work, it isn&rsquo;t ideal for our purposes. The problem is this: Where we want to search a fixed-length buffer for the first occurrence of a string, <b>strstr()</b> searches a <i>string</i> for the first occurrence of another string.</p>
