## Detailed Description

Class containing the system information on a file path.

Information can be obtained on any directory entry event if it is not a "file" in the strictest sense. Sub-directories, devices etc may also have information retrieved.

## Member Enumeration Documentation

enum PFileInfo::FileTypes

All types that a particular file path may be.

Not all platforms support all of the file types. For example under DOS no file may be of the type `SymbolicLink`.

Enumerator
RegularFile | Ordinary disk file.
SymbolicLink | File path is a symbolic link.
SubDirectory | File path is a sub-directory.
CharDevice | File path is a character device name.
BlockDevice | File path is a block device name.
Fifo | File path is a fifo (pipe) device.
SocketDevice | File path is a socket device.
UnknownFileType | File path is of an unknown type.
AllFiles | Mask for all file types.

enum PFileInfo::Permissions

File access permissions for the file.

Enumerator
WorldExecute | File has world execute permission.
WorldWrite | File has world write permission.
WorldRead | File has world read permission.
GroupExecute | File has group execute permission.
GroupWrite | File has group write permission.
GroupRead | File has group read permission.
UserExecute | File has owner execute permission.
UserWrite | File has owner write permission.
UserRead | File has owner read permission.
AllPermissions | All possible permissions.
DefaultPerms | Owner read & write plus group and world read permissions.
DefaultDirPerms | Owner read & write & execute plus group and world read & exectute permissions.

## Member Data Documentation

PTime PFileInfo::accessed

Time of last access to the file.

Not all platforms support a separate access time in which case the last modified time is returned.

PTime PFileInfo::created

Time of file creation of the file.

Not all platforms support a separate creation time in which case the last modified time is returned.

PBoolean PFileInfo::hidden

File is a hidden file.

What constitutes a hidden file is platform dependent, for example under unix it is a file beginning with a '.' character while under MS-DOS there is a file system attribute for it.

PTime PFileInfo::modified

Time of last modifiaction of the file.

int PFileInfo::permissions

A bit mask of all the file acces permissions.

See the `Permissions` enum# for the possible bit values.

Not all platforms support all permissions.

PUInt64 PFileInfo::size

Size of the file in bytes.

This is a quadword or 8 byte value to allow for files greater than 4 gigabytes.

FileTypes PFileInfo::type

File type for this file. Only one bit is set at a time here.
