DESCRIPTION

114   Copying to and from struct stat
115     The function archive_entry_stat() converts the various fields stored in
116     the archive entry to the format used by stat(2).  The return value
117     remains valid until either archive_entry_clear() or archive_entry_free()
118     is called.  It is not affected by calls to the set accessor functions.
119     It currently sets the following values in struct stat: st_atime,
120     st_ctime, st_dev, st_gid, st_ino, st_mode, st_mtime, st_nlink, st_rdev,
121     st_size, st_uid.  In addition, st_birthtime and high-precision informa‐
122     tion for time-related fields will be included on platforms that support
123     it.
124
125     The function archive_entry_copy_stat() copies fields from the platform's
126     struct stat.  Fields not provided by struct stat are unchanged.
127
128   General accessor functions
129     The functions archive_entry_filetype() and archive_entry_set_filetype()
130     get respectively set the filetype.  The file type is one of the following
131     constants:
132           AE_IFREG   Regular file
133           AE_IFLNK   Symbolic link
134           AE_IFSOCK  Socket
135           AE_IFCHR   Character device
136           AE_IFBLK   Block device
137           AE_IFDIR   Directory
138           AE_IFIFO   Named pipe (fifo)
139     Not all file types are supported by all platforms.  The constants used by
140     stat(2) may have different numeric values from the corresponding con‐
141     stants above.
142
143     The functions archive_entry_mode() and archive_entry_set_mode() get/set a
144     combination of file type and permissions and provide the equivalent of
145     st_mode.  Use of archive_entry_filetype() and archive_entry_perm() for
146     getting and archive_entry_set_filetype() and archive_entry_set_perm() for
147     setting is recommended.
148
149     The function archive_entry_size() returns the file size, if it has been
150     set, and 0 otherwise.  archive_entry_size() can be used to query that
151     status.  archive_entry_set_size() and archive_entry_unset_size() set and
152     unset the size, respectively.
153
154     The number of references (hardlinks) can be obtained by calling
155     archive_entry_nlink() and set with archive_entry_set_nlink().
156
157   Identifying unique files
158     The functions archive_entry_dev() and archive_entry_ino64() are used by
159     archive_entry_linkify(3) to find hardlinks.  The pair of device and inode
160     is supposed to identify hardlinked files.
161
162     The device major and minor number can be obtained independently using
163     archive_entry_devmajor() and archive_entry_devminor().  The device can be
164     set either via archive_entry_set_dev() or by the combination of major and
165     minor number using archive_entry_set_devmajor() and
166     archive_entry_set_devminor().
167
168     The inode number can be obtained using archive_entry_ino().  This is a
169     legacy interface that uses the platform ino_t, which may be very small.
170     To set the inode number, archive_entry_set_ino64() is the preferred
171     interface.
172
173   Accessor functions for block and character devices
174     Block and character devices are characterised either using a device num‐
175     ber or a pair of major and minor number.  The combined device number can
176     be obtained with archive_device_rdev() and set with
177     archive_device_set_rdev().  The major and minor numbers are accessed by
178     archive_device_rdevmajor(), archive_device_rdevminor()
179     archive_device_set_rdevmajor() and archive_device_set_rdevminor().
180
181     The process of splitting the combined device number into major and minor
182     number and the reverse process of combing them differs between platforms.
183     Some archive formats use the combined form, while other formats use the
184     split form.
