+.Sh SYNOPSIS
+.Fd #include <util.h>
+.Ft char *
+.Fn readlabelfs "char *device" "int verbose"
+.Sh DESCRIPTION
+The
+.Fn readlabelfs
+function attempts to determine the filesystem type of the disk
+partition specified by

+arguments within

+and similar high-level filesystem utilties.
+.Pp
+If the
+.Ar verbose
+argument is not 0,
+.Fn readlabelfs
+will print appropiate error messages before returning.  Otherwise, it
+produces no output on the terminal.
+.Pp
+.Sh RETURN VALUES
+.Fn readlabelfs
+returns NULL upon error, or a valid filesystem type upon success.
+.Sh HISTORY
+.Fn readlabelfs
+first appeared in OpenBSD 2.0.
