The function () converts the various fields stored in the archive entry to the format used by stat(2). The return value remains valid until either () or () is called. It is not affected by calls to the set accessor functions. It currently sets the following values in struct stat: st_atime, st_ctime, st_dev, st_gid, st_ino, st_mode, st_mtime, st_nlink, st_rdev, st_size, st_uid. In addition, st_birthtime and high-precision information for time-related fields will be included on platforms that support it.

The function () copies fields from the platform's struct stat. Fields not provided by struct stat are unchanged.

The functions () and () get respectively set the filetype. The file type is one of the following constants:

AE_IFREG
Regular file
AE_IFLNK
Symbolic link
AE_IFSOCK
Socket
AE_IFCHR
Character device
AE_IFBLK
Block device
AE_IFDIR
Directory
AE_IFIFO
Named pipe (fifo)
Not all file types are supported by all platforms. The constants used by stat(2) may have different numeric values from the corresponding constants above.

The functions () and () get/set a combination of file type and permissions and provide the equivalent of st_mode. Use of archive_entry_filetype() and () for getting and archive_entry_set_filetype() and () for setting is recommended.

The function () returns the file size, if it has been set, and 0 otherwise. archive_entry_size() can be used to query that status. () and () set and unset the size, respectively.

The number of references (hardlinks) can be obtained by calling () and set with ().

The functions () and () are used by archive_entry_linkify(3) to find hardlinks. The pair of device and inode is supposed to identify hardlinked files.

The device major and minor number can be obtained independently using () and (). The device can be set either via () or by the combination of major and minor number using () and ().

The inode number can be obtained using (). This is a legacy interface that uses the platform ino_t, which may be very small. To set the inode number, () is the preferred interface.

Block and character devices are characterised either using a device number or a pair of major and minor number. The combined device number can be obtained with () and set with (). The major and minor numbers are accessed by (), () () and ().

The process of splitting the combined device number into major and minor number and the reverse process of combing them differs between platforms. Some archive formats use the combined form, while other formats use the split form.
