The dates in the original file may or may not be zero padded, so April is sometimes "04" and other times simply "4".

APR::PerlIO -- Perl IO layer for APR
Synopsis
# under mod_perl
use APR::PerlIO ();
sub handler {
my $r = shift;
die "This Perl build doesn't support PerlIO layers"
unless APR::PerlIO::PERLIO_LAYERS_ARE_ENABLED;
open my $fh, ">:APR", $filename, $r->pool or die $!;
# work with $fh as normal $fh
close $fh;
return Apache2::Const::OK;
}
# outside mod_perl
% perl -MAPR -MAPR::PerlIO -MAPR::Pool -le
'open my $fh, ">:APR", "/tmp/apr", APR::Pool->new or die "$!";
print $fh "whoah!";
close $fh;'
Description
"APR::PerlIO" implements a Perl IO layer using APR's file manipulation API internally.
Why do you want to use this? Normally you shouldn't, probably it won't be faster than Perl's default layer. It's only useful when you need
to manipulate a filehandle opened at the APR side, while using Perl.
Normally you won't call open() with APR layer attribute, but some mod_perl functions will return a filehandle which is internally hooked to
APR. But you can use APR Perl IO directly if you want.
Prerequisites
Not every Perl will have full "APR::PerlIO" functionality available.
Before using the Perl IO APR layer one has to check whether it's supported by the used APR/Perl build. Perl 5.8.x or higher with perlio
enabled is required. You can check whether your Perl fits the bill by running:
% perl -V:useperlio
useperlio='define';
It should say define.
If you need to do the checking in the code, there is a special constant provided by "APR::PerlIO", which can be used as follows:
use APR::PerlIO ();
die "This Perl build doesn't support PerlIO layers"
unless APR::PerlIO::PERLIO_LAYERS_ARE_ENABLED;
Notice that loading "APR::PerlIO" won't fail when Perl IO layers aren't available since "APR::PerlIO" provides functionality for Perl
builds not supporting Perl IO layers.
Constants
"APR::PerlIO::PERLIO_LAYERS_ARE_ENABLED"
See Prerequisites.
API
Most of the API is as in normal perl IO with a few nuances listed in the following sections.
META: need to rework the exception mechanism here. Current success in using errno ($!) being set (e.g. on open()) is purely accidental and
not guaranteed across all platforms and functions. So don't rely on $!. Will use "APR::Error" for that purpose.
"open"
Open a file via APR Perl IO layer.
open my $fh, ">:APR", $filename, $r->pool or die $!;
arg1: $fh ( GLOB filehandle )
The filehandle.
arg2: $mode ( string )
The mode to open the file, constructed from two sections separated by the ":" character: the first section is the mode to open the file
under (>, <, etc) and the second section must be a string APR. For more information refer to the open entry in the perlfunc manpage.
arg3: $filename ( string )
The path to the filename to open
arg4: $p ( "APR::Pool" )
The pool object to use to allocate APR::PerlIO layer.
ret: ( integer )
success or failure value (boolean).
since: 2.0.00
"seek"
Sets $fh's position, just like the "seek()" Perl call:
seek($fh, $offset, $whence);
If $offset is zero, "seek()" works normally.
However if $offset is non-zero and Perl has been compiled with with large files support ("-Duselargefiles"), whereas APR wasn't, this
function will croak. This is because largefile size "Off_t" simply cannot fit into a non-largefile size "apr_off_t".
To solve the problem, rebuild Perl with "-Uuselargefiles". Currently there is no way to force APR to build with large files support.
since: 2.0.00
C API
The C API provides functions to convert between Perl IO and APR Perl IO filehandles.
