Using longjmp() from a signal handler or modifying the handling of SIGALRM while sleeping will cause undefined results. </pre> <hr> <h3>SEE ALSO </h3><p> <a href=signal.htm>signal</a>, <a href=alarm.htm>alarm</a>, <pre> <h3>GNU April 7, 1993 1 </h3> </pre> <P> <hr> <p> <center> <table border=2 width=80%> <tr align=center> <td width=25%> <a href=../index.htm>Top</a> </td><td width=25%> <a href=../master_index.html>Master Index</a> </td><td width=25%> <a href=../SYNTAX/keywords.html>Keywords</a> </td><td width=25%> <a href=../FUNCTIONS/index.htm>Functions</a> </td> </tr> </table> </center> <p> <hr> This manual page was brought to you by <i>mjl_man V-2.0</i>
