()archive_read_support_format_tar
() enables support
for a variety of standard tar formats, old-style tar, ustar, pax
interchange format, and many common variants.archive_read_support_format_all

()archive_format
()
after reading the first time and pass the resulting code to this function
to selectively enable only the necessary format support. Note: In
statically-linked executables, this will cause your program to include
support for every format. If executable size is a concern, you may wish to
avoid using this function.archive_read_support_format_empty
()archive_read_support_format_raw
()archive_read_support_format_all
() in order to
avoid erroneous handling of damaged archives.These functions return ARCHIVE_OK
on
success, or ARCHIVE_FATAL
.
Detailed error codes and textual descriptions are available from
the archive_errno
() and
archive_error_string
() functions.
tar(1), archive_read_data(3), archive_read_filter(3), archive_read_set_options(3), archive_util(3), libarchive(3), tar(5)
Many traditional archiver programs treat empty files as valid empty archives. For example, many implementations of tar(1) allow you to append entries to an empty file. Of course, it is impossible to determine the format of an empty file by inspecting the contents, so this library treats empty files as having a special “empty” format.
Using the “raw” handler together with any other handler will often work but can produce surprising results.
