Filesys::POSIX::Real - Portal to actual underlying filesystem
use Filesys::POSIX; use Filesys::POSIX::Real; my $fs = Filesys::POSIX->new(Filesys::POSIX::Real->new, 'path' => '/home/foo/test', 'noatime' => 1 );
This module implements the filesystem device type which provides a portal to the actual system's underlying filesystem.
The following value is mandatory:
path
The path, in the real filesystem, upon which the new filesystem to be mounted will be based.
The following value is not mandatory:
sticky
When set to a value evaluating to true, any updates to certain attributes of any inode brought to life by this module are not committed to disk. When this flag is used, the following calls only affect the inode in memory, but not on disk:
$fs->chmod
$fs->chown
$fs->symlink
Furthermore, only the following attributes are synced from disk onto their corresponding memory inodes:
size
atime
mtime
ctime
Filesys::POSIX::Real->new
Create a new, uninitialized filesystem.
$fs->init(%data)
Initializes the new filesystem. A reference to the %data argument is saved in the filesystem object.
%data
Exceptions will be thrown for the following:
EINVAL (Invalid argument)
No value was specified for $data{'path'}.
$data{'path'}
ENOTDIR (Not a directory)
The path specified in $data{'path'} on the real filesystem does not correspond to an actual directory.
