|
||||
== DESCRIPTION ==
|
||||
=== Copying to and from ''struct'' stat===
|
||||
The function
|
||||
'''archive_entry_stat'''()
|
||||
converts the various fields stored in the archive entry to the format
|
||||
used by
|
||||
[[stat(2)|http://www.freebsd.org/cgi/man.cgi?query=stat&sektion=2]].
|
||||
The return value remains valid until either
|
||||
'''archive_entry_clear'''()
|
||||
or
|
||||
'''archive_entry_free'''()
|
||||
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
|
||||
'''archive_entry_copy_stat'''()
|
||||
copies fields from the platform's
|
||||
''struct'' stat.
|
||||
Fields not provided by
|
||||
''struct'' stat
|
||||
are unchanged.
|
||||
=== General accessor functions===
|
||||
The functions
|
||||
'''archive_entry_filetype'''()
|
||||
and
|
||||
'''archive_entry_set_filetype'''()
|
||||
get respectively set the filetype.
|
||||
The file type is one of the following constants:
|
||||
<dl>
|
||||
<dt>AE_IFREG</dt><dd>
|
||||
Regular file
|
||||
</dd><dt>AE_IFLNK</dt><dd>
|
||||
Symbolic link
|
||||
</dd><dt>AE_IFSOCK</dt><dd>
|
||||
Socket
|
||||
</dd><dt>AE_IFCHR</dt><dd>
|
||||
Character device
|
||||
</dd><dt>AE_IFBLK</dt><dd>
|
||||
Block device
|
||||
</dd><dt>AE_IFDIR</dt><dd>
|
||||
Directory
|
||||
</dd><dt>AE_IFIFO</dt><dd>
|
||||
Named pipe (fifo)
|
||||
</dd></dl>
|
||||
Not all file types are supported by all platforms.
|
||||
The constants used by
|
||||
[[stat(2)|http://www.freebsd.org/cgi/man.cgi?query=stat&sektion=2]]
|
||||
may have different numeric values from the
|
||||
corresponding constants above.
|
||||
|
||||
The functions
|
||||
'''archive_entry_mode'''()
|
||||
and
|
||||
'''archive_entry_set_mode'''()
|
||||
get/set a combination of file type and permissions and provide the
|
||||
equivalent of
|
||||
''st_mode''.
|
||||
Use of
|
||||
'''archive_entry_filetype'''()
|
||||
and
|
||||
'''archive_entry_perm'''()
|
||||
for getting and
|
||||
'''archive_entry_set_filetype'''()
|
||||
and
|
||||
'''archive_entry_set_perm'''()
|
||||
for setting is recommended.
|
||||
|
||||
The function
|
||||
'''archive_entry_size'''()
|
||||
returns the file size, if it has been set, and 0 otherwise.
|
||||
'''archive_entry_size'''()
|
||||
can be used to query that status.
|
||||
'''archive_entry_set_size'''()
|
||||
and
|
||||
'''archive_entry_unset_size'''()
|
||||
set and unset the size, respectively.
|
||||
|
||||
The number of references (hardlinks) can be obtained by calling
|
||||
'''archive_entry_nlinks'''()
|
||||
and set with
|
||||
'''archive_entry_set_nlinks'''().
|
||||
=== Identifying unique files===
|
||||
The functions
|
||||
'''archive_entry_dev'''()
|
||||
and
|
||||
'''archive_entry_ino64'''()
|
||||
are used by
|
||||
[[ManPagerchiventryinkify3]]
|
||||
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
|
||||
'''archive_entry_devmajor'''()
|
||||
and
|
||||
'''archive_entry_devminor'''().
|
||||
The device can be set either via
|
||||
'''archive_entry_set_dev'''()
|
||||
or by the combination of major and minor number using
|
||||
'''archive_entry_set_devmajor'''()
|
||||
and
|
||||
'''archive_entry_set_devminor'''().
|
||||
|
||||
The inode number can be obtained using
|
||||
'''archive_entry_ino'''().
|
||||
This is a legacy interface that uses the platform
|
||||
''ino_t'',
|
||||
which may be very small.
|
||||
To set the inode number,
|
||||
'''archive_entry_set_ino64'''()
|
||||
is the preferred interface.
|
||||
=== Accessor functions for block and character devices===
|
||||
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
|
||||
'''archive_device_rdev'''()
|
||||
and set with
|
||||
'''archive_device_set_rdev'''().
|
||||
The major and minor numbers are accessed by
|
||||
'''archive_device_rdevmajor'''(),
|
||||
'''archive_device_rdevminor'''()
|
||||
'''archive_device_set_rdevmajor'''()
|
||||
and
|
||||
'''archive_device_set_rdevminor'''().
|
||||
|
||||
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.
