Hello,
I checked and $nf is set to 1 on my machine. Odd.
I also added code to count the number of times this occurs and it happens thousands of times.
I don't think you understood what sgifford said. When $nf is 1, there is no error. This is exactly what should be expected. You only look at $! to see what the error is after there is an error. The perl variable $! and the related C variable errno do not get reset to 0 when there is a successfull call. They will hold the previous error value until another error happens or the program specificly sets them. The moral is: Don't look at $! to see if there has been an error. Only look at it to see what error occurred after something else indicates that there has indeed been an error.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
