<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>

    <i>Sysfatal</i> prints to standard error the name of the running program,
    a colon and a space, the message described by the <a href="../man3/print.html"><i>print</i>(3)</a> format
    string <i>fmt</i> and subsequent arguments, and a newline. It then calls
    <a href="../man3/exits.html"><i>exits</i>(3)</a> with the formatted message as argument. The program&#8217;s
    name is the value of <tt><font size=+1>argv0</font></tt>, which will be set if the
    program uses the <a href="../man3/arg.html"><i>arg</i>(3)</a> interface to process its arguments. If
    <tt><font size=+1>argv0</font></tt> is null, it is ignored and the following colon and space
    are suppressed.<br>
