+in this respect and is described at the end.
+.Pp
 The
 .Fn vn_fullpath
-function
-is implemented by inspecting the VFS name cache, and attempting to
-reconstruct a path from the process root to the object.
+function returns a path relative to the root directory of the process associated
+with the passed thread pointer.
+That root directory is either the system's or the thread's process' containing
+jail's root directory, or some descendant directory of such established by some
+.Xr chroot 2
+call.
+The
+.Fn vn_fullpath_jail
+function returns a path relative to the passed thread's process' current jail's
+root, ignoring intervening
+.Xr chroot 2
+calls possibly made inside that jail.
+The
+.Fn vn_fullpath_global
+function returns the full path from the system root, ignoring all jail roots and
+.Xr chroot 2
+calls.
+.Pp
+Paths that the kernel intends to communicate to the passed user thread should
+exclusively be obtained via
+.Fn vn_fullpath .
+Paths obtained via
+.Fn vn_fullpath_jail
+or
+.Fn vn_fullpath_global
+are only useful for specific kernel checks or auditing purposes.
 .Pp
+All these functions are implemented by inspecting the VFS name cache, and
+attempting to reconstruct a path from the process root to the object.
 This process is necessarily unreliable for several reasons: intermediate
 entries in the path may not be found in the cache; files may have more
 than one name (hard links), not all file systems use the name cache
