+DESCRIPTION
+     archive_read_data()
+	     Read data associated with the header just read.  Internally, this
+	     is a convenience function that calls archive_read_data_block()
+	     and fills any gaps with nulls so that callers see a single con‐
+	     tinuous stream of data.
+     archive_read_data_block()
+	     Return the next available block of data for this entry.  Unlike
+	     archive_read_data(), the archive_read_data_block() function
+	     avoids copying data and allows you to correctly handle sparse
+	     files, as supported by some archive formats.  The library guaran‐
+	     tees that offsets will increase and that blocks will not overlap.
+	     Note that the blocks returned from this function can be much
+	     larger than the block size read from disk, due to compression and
+	     internal buffer optimizations.
+     archive_read_data_skip()
+	     A convenience function that repeatedly calls
+	     archive_read_data_block() to skip all of the data for this ar‐
+	     chive entry.  Note that this function is invoked automatically by
+	     archive_read_next_header2() if the previous entry was not com‐
+	     pletely consumed.
+     archive_read_data_into_fd()
+	     A convenience function that repeatedly calls
+	     archive_read_data_block() to copy the entire entry to the pro‐
+	     vided file descriptor.
+
+RETURN VALUES
+     Most functions return zero on success, non-zero on error.	The possible
+     return codes include: ARCHIVE_OK (the operation succeeded), ARCHIVE_WARN
+     (the operation succeeded but a non-critical error was encountered),
+     ARCHIVE_EOF (end-of-archive was encountered), ARCHIVE_RETRY (the opera‐
+     tion failed but can be retried), and ARCHIVE_FATAL (there was a fatal er‐
+     ror; the archive should be closed immediately).
+
+     archive_read_data() returns a count of bytes actually read or zero at the
+     end of the entry.	On error, a value of ARCHIVE_FATAL, ARCHIVE_WARN, or
+     ARCHIVE_RETRY is returned.
+
+ERRORS
+     Detailed error codes and textual descriptions are available from the
+     archive_errno() and archive_error_string() functions.
