-.Sh EXAMPLES
-The following sets

-.Pp
-The following sets

-NUL terminates the destination string when the length of the source
-string is less than the length parameter.

-.Pp
-The following copies as many characters from
-.Va input
-to
-.Va buf
-as will fit and NUL terminates the result.
-Because

-does
