As stated before sysopen comes with more precision than open.
sysopen helps avoiding race-conditions.
Consider the following snippet:
if (-e $file) {
open(FH,">","$file") or die $!;
}
It's a two step process:
- File test
- open
sysopen needs only one step (kind a simplistic, but you should get the message).
use Fcntl;
sysopen(FH, $file, O_WRONLY|O_TRUNC|O_CREAT, 0600)
or die $!;
HTH,

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).
