The string that fgets() produces is always <strong>NULL</strong>-terminated. fgets() will stop when it reaches the end of a line, in which case <em>str</em> will contain that newline character. Otherwise, fgets() will stop when it reaches <em>num</em> - 1 characters or encounters the <strong>EOF</strong> character. fgets() returns <em>str</em> on success, and <strong>NULL</strong> on an error.</p> <div class="related-name-format"> Related topics: </div> <div class="related-content"> <a href="fputs.html">fputs</a><br> <a href="fscanf.html">fscanf</a><br> <a href="gets.html">gets</a><br> <a href="scanf.html">scanf</a> </div> </div> </td> </tr> </table></body></html>⌨️ 快捷键说明
