=head1 NAME
Cwd - get pathname of current working directory
=head1 SYNOPSIS
use Cwd;
my $dir = getcwd;
use Cwd 'abs_path';
my $abs_path = abs_path($file);
=head1 DESCRIPTION
This module provides functions for determining the pathname of the
current working directory. It is recommended that getcwd (or another
*cwd() function) be used in I code to ensure portability.
By default, it exports the functions cwd(), getcwd(), fastcwd(), and
fastgetcwd() (and, on Win32, getdcwd()) into the caller's namespace.
=head2 getcwd and friends
Each of these functions are called without arguments and return the
absolute path of the current working directory.
=over 4
=item getcwd
my $cwd = getcwd();
Returns the current working directory.
Exposes the POSIX function getcwd(3) or re-implements it if it's not
available.
=item cwd
my $cwd = cwd();
The cwd() is the most natural form for the current architecture. For
most systems it is identical to `pwd` (but without the trailing line
terminator).
=item fastcwd
my $cwd = fastcwd();
A more dangerous version of getcwd(), but potentially faster.
It might conceivably chdir() you out of a directory that it can't
chdir() you back into. If fastcwd encounters a problem it will return
undef but will probably leave you in a different directory. For a
measure of extra security, if everything appears to have worked, the
fastcwd() function will check that it leaves you in the same directory
that it started in. If it has changed it will C with the message
"Unstable directory path, current directory changed
unexpectedly". That should never happen.
=item fastgetcwd
my $cwd = fastgetcwd();
The fastgetcwd() function is provided as a synonym for cwd().
=item getdcwd
my $cwd = getdcwd();
my $cwd = getdcwd('C:');
The getdcwd() function is also provided on Win32 to get the current working
directory on the specified drive, since Windows maintains a separate current
working directory for each drive. If no drive is specified then the current
drive is assumed.
This function simply calls the Microsoft C library _getdcwd() function.
=back
=head2 abs_path and friends
These functions are exported only on request. They each take a single
argument and return the absolute pathname for it. If no argument is
given they'll use the current working directory.
=over 4
=item abs_path
my $abs_path = abs_path($file);
Uses the same algorithm as getcwd(). Symbolic links and relative-path
components ("." and "..") are resolved to return the canonical
pathname, just like realpath(3).
=item realpath
my $abs_path = realpath($file);
A synonym for abs_path().
=item fast_abs_path
my $abs_path = fast_abs_path($file);
A more dangerous, but potentially faster version of abs_path.
