passing "stderr " to a subroutine..
This is perl, v5.6.1 built for MSWin32-x86-multi-thread
-----------
i thought to pass the stderr to the subroutine which writes in a log file..
when i use
&log_message(\*STDERR);
in the log file instead of the error messages, i am getting only this word
____________::GLOB(0x1ab507c)
and when i use
&log_message(*STDERR);
i got
____________::*main::STDERR
1). i like to know how to pass the error messages into a subroutine(which writes the messages passed to it into a log file..)
2).or how to assign STDERR to a file handle?
thanks in advance..

xslt_set_log
XSLT_SET_LOG(3) 1 XSLT_SET_LOG(3)
xslt_set_log - Set the log file to write log messages to
SYNOPSIS
void xslt_set_log (resource $xh, [mixed $log])
DESCRIPTION
This function allows you to set the file in which you want XSLT log messages to, XSLT log messages are different than error messages, in
that log messages are not actually error messages but rather messages related to the state of the XSLT processor. They are useful for
debugging XSLT, when something goes wrong.
By default logging is disabled, in order to enable logging you must first call xslt_set_log(3) with a boolean parameter which enables log-
ging, then if you want to set the log file to debug to, you must then pass it a string containing the filename.
PARAMETERS
o $
xh -The XSLT processor link identifier, created with xslt_create(3).
o $log
- This parameter is either a boolean value which toggles logging on and off, or a string containing the logfile in which log
errors too.
RETURN VALUES
No value is returned.
NOTES
Note
Please note that file:// is needed in front of the path when using Windows.
EXAMPLES
Example #1
Using the XSLT Logging features
<?php
$xh = xslt_create();
xslt_set_log($xh, true);
xslt_set_log($xh, getcwd() . '/myfile.log');
$result = xslt_process($xh, 'dog.xml', 'pets.xsl');
echo $result;
xslt_free($xh);
?>
