The questions will be:
- Why is this generating a diagnostic warning?
- What can I do about it?
I've inherited a huge thing that uses lots of dbmopen() and dbmclose(). I know this is now superceded by tie(), but I'd like to understand what is going on before I decide to go changing things willy-nilly.
The following snippet demonstrates something I'm running into when I turn on WARNINGS:
|
#!/usr/bin/perl -w
use strict;
my $TSTFNM = "test-dbm-data";
my $TSTACC = 0666;
my $opnret = dbmopen(my %TSTDBM, $TSTFNM, $TSTACC);
print "DBM Open: '$opnret'\n";
my $cloret = dbmclose(%TSTDBM);
exit;
__END__
|
I get the following results:
|
DBM Open: 'AnyDBM_File=SCALAR(0x1982e8c)'
<BR>untie attempted while 1 inner references still exist at D:\Steve\D
+ev\test-dbm.pl line 10.
|
If I take out the perl -w, no problems reported.
- Why is this generating a diagnostic warning?
- What can I do about it?
I've poked around Google and done a search here at PerlMonks and I'm landing on neither a useful problem description nor a useful solution.
So I thought I'd pray for divine intervention. :-)
Many thanks for your time and assistance.

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).

or How to display code and escape characters
are good places to start.
