The argument string s is printed first, then a colon and a blank, then the message and a new-line. To be of most use, the argument string should include the name of the program that incurred the error. The error number is taken from the external vari- able errno, which is set when errors occur but not cleared when non-erroneous calls are made. <h3>CONFORMING TO </h3> ANSI C, POSIX </pre> <hr> <h3>SEE ALSO </h3><p> <a href=errno.htm>errno</a>, <a href=strerror.htm>strerror</a>, <pre> March 16, 1995 1 </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>
