The function <em>compare</em> should return negative if its first argument is less than its second, zero if equal, and positive if greater. The items in the array <em>buf</em> should be in ascending order. The return value of bsearch() is a pointer to the matching item, or <strong>NULL</strong> if none is found.</p> <div class="related-name-format"> Related topics: </div> <div class="related-content"> <a href="qsort.html">qsort</a> </div> </div> </td> </tr> </table></body></html>⌨️ 快捷键说明
