+.Sh DESCRIPTION
+The
+.Fn wcslcpy
+and
+.Fn wcslcat
+functions copy and concatenate wide strings respectively.
+They are designed to be safer, more consistent, and less error prone
+replacements for
+.Xr wcsncpy 3
+and
+.Xr wcsncat 3 .
+Unlike those functions,
+.Fn wcslcpy
+and
+.Fn wcslcat
+take the full size of the buffer (not just the length) and guarantee to
+terminate the result with a null wide character (as long as
+.Fa size
+is larger than 0 or, in the case of
+.Fn wcslcat ,
+as long as there is at least one wide character free in
+.Fa dst ) .
+Note that a wide character for the null wide character should be included in
+.Fa size .
+Also note that
+.Fn wcslcpy
+and
+.Fn wcslcat
+only operate on wide strings that are terminated with a null wide character
+(L'\e0').
+This means that for
+.Fn wcslcpy
+.Fa src
+must be terminated with a null wide character and for
+.Fn wcslcat
+both
+.Fa src
+and
+.Fa dst
+must be terminated with a null wide character.
+.Pp
+The
+.Fn wcslcpy
+function copies up to
+.Fa size
+\(mi 1 wide characters from the wide string
+.Fa src
+to
+.Fa dst ,
+terminating the result with a null wide character.
+.Pp
+The
+.Fn wcslcat
+function appends the wide string
+.Fa src
+to the end of
+.Fa dst .
+It will append at most
+.Fa size
+\(mi wcslen(dst) \(mi 1 wide characters, terminating the result with a null
+wide character.
+.Sh RETURN VALUES
+The
+.Fn wcslcpy
+and
+.Fn wcslcat
+functions return the total length of the wide string they tried to create.
+For
+.Fn wcslcpy
+that means the length of
+.Fa src .
+For
+.Fn wcslcat
+that means the initial length of
+.Fa dst
+plus
+the length of
+.Fa src .
+While this may seem somewhat confusing, it was done to make
+truncation detection simple.
+.Pp
+Note, however, that if
+.Fn wcslcat
+traverses
+.Fa size
+wide characters without finding a null wide character, the length of the
+string is considered to be
+.Fa size
+and the destination wide string will not be terminated with a null wide
+character (since there was no space for it).
+This keeps
+.Fn wcslcat
+from running off the end of a wide string.
+In practice this should not happen (as it means that either
+.Fa size
+is incorrect or that
+.Fa dst
+is not terminated with a null wide character).
+The check exists to prevent potential security problems in incorrect code.

+.Fa s1
+against the wide string

+.Sh RETURN VALUES
+The

+In this implementation
+.Fn wmemcpy

+.Xr bcopy 3 ,
+and therefore the buffers may overlap.
+On other systems, copying overlapping buffers may produce surprises.
+A simpler solution is to not use
