<dl>
<dt><strong><a name="item_set_log_handler" id="item_set_log_handler">set_log_handler SUB</a></strong></dt>
<dd>
<p>Set <em>SUB</em> as the subroutine to be called on any Redland error, warning or log message. The subroutine must have the followign signature:</p>
</dd>
<dd>
<pre>
sub handler ($$$$$$$$$) {
my($code, $level, $facility, $message, $line, $column, $byte, $file, $uri)=@_;
# int error code
# int log level
# int facility causing the error (parsing, serializing, ...)
# string error message
# int line number (<0 if not relevant)
# int column number (<0 if not relevant)
# int byte number (<0 if not relevant)
# string file name or undef
# string URI or undef
# ...do something with the information ...
};
</pre></dd>
<dd>
<pre>
RDF::Redland::set_log_handler(\&handler);
</pre></dd>
</dl>
<div style="margin-left: 2em">
<dl>
<dt><strong><a name="item_reset_log_handler" id="item_reset_log_handler">reset_log_handler</a></strong></dt>
</dl>
</div>
<p>Reset redland to use the default logging handler, typically printing the message to stdout or stderr and exiting on a fatal error.</p>
<div style="margin-left: 2em">
<dl>
<dt><strong><a name="item_set_error_handler" id="item_set_error_handler">set_error_handler SUB</a></strong></dt>
</dl>
</div>
<p>The method set_log_handler is much more flexible than this and includes this functionality.</p>
<p>Set <em>SUB</em> as the subroutine to be called on a Redland error with the error message as the single argument. For example:</p>
<pre>
RDF::Redland::set_error_handler(sub {
my $msg=shift;
# Do something with $msg
});
</pre>
<p>The default if this is not set, is to run die $msg</p>
<div style="margin-left: 2em">
<dl>
<dt><strong><a name="item_set_warning_handler" id="item_set_warning_handler">set_warning_handler SUB</a></strong></dt>
</dl>
</div>
<p>The method set_log_handler is much more flexible than this and includes this functionality.</p>
<p>Set <em>SUB</em> as the subroutine to be called on a Redland warning with the warning message as the single argument. For example:</p>
<pre>
RDF::Redland::set_warning_handler(sub {
my $msg=shift;
# Do something with $msg
});
</pre>
<p>The default if this is not set, is to run warn $msg</p>
