+.Sh DESCRIPTION
+The string functions
+manipulate strings terminated by a
+null byte.
+.Pp
+See the specific manual pages for more information.
+For manipulating variable length generic objects as byte
+strings (without the null byte check), see
+.Xr bstring 3 .
+.Pp
+Except as noted in their specific manual pages,
+the string functions do not test the destination
+for size limitations.
