+.Os
+.Sh NAME
+.Nm archive_write_finish_entry
+.Nd functions for creating archives
+.Sh LIBRARY
+Streaming Archive Library (libarchive, -larchive)
+.Sh SYNOPSIS
+.In archive.h
+.Ft int
+.Fn archive_write_finish_entry "struct archive *"
+.Sh DESCRIPTION
+Close out the entry just written.
+In particular, this writes out the final padding required by some formats.
+Ordinarily, clients never need to call this, as it
+is called automatically by
+.Fn archive_write_header
+and
+.Fn archive_write_close
+as needed.
+For
+.Tn archive_write_disk
+handles, this flushes pending file attribute changes like modification time.
+.\" .Sh EXAMPLE
+.Sh RETURN VALUES
+This function returns
+.Cm ARCHIVE_OK
+on success, or one of several non-zero
+error codes for errors.
+Specific error codes include:
+.Cm ARCHIVE_RETRY
+for operations that might succeed if retried,
+.Cm ARCHIVE_WARN
+for unusual conditions that do not prevent further operations, and
+.Cm ARCHIVE_FATAL
+for serious errors that make remaining operations impossible.
+.\"
+.Sh ERRORS
+Detailed error codes and textual descriptions are available from the
+.Fn archive_errno
+and
+.Fn archive_error_string
+functions.
