+.Nd copy wide strings
+.Sh SYNOPSIS
+.Fd #include <wchar.h>
+.Ft wchar_t *
+.Fn wcscpy "wchar_t * restrict dst" "const wchar_t * restrict src"
+.Ft wchar_t *

+.Sh DESCRIPTION
+The
+.Fn wcscpy
+and
+.Fn wcsncpy
+functions copy the wide string
+.Fa src
+to
+.Fa dst
+(including the terminating null wide character).
+.Pp
+The
+.Fn wcsncpy
+function copies not more than
+.Fa len
+wide characters to
+.Fa dst ,
+appending null wide characters if the length of
+.Fa src
+is less than
+.Fa len ,
+and
+.Em not
+terminating
+.Fa dst
+if the length of
+.Fa src
+is greater than or equal to
+.Fa len .
+.Sh RETURN VALUES
+The
+.Fn wcscpy
+and
+.Fn wcsncpy
+functions return
+.Fa dst .
+.Sh SEE ALSO
+.Xr strcpy 3 ,
+.Xr strlcpy 3 ,
+.Xr wcscat 3 ,
+.Xr wcslcpy 3 ,
+.Xr wmemcpy 3 ,
+.Xr wmemmove 3
+.Sh STANDARDS
+The
+.Fn wcscpy
+and
+.Fn wcsncpy
+functions conform to
+.St -isoC-99
+and were first introduced in
+.St -isoC-amd1 .
+.Sh HISTORY
+The
+.Fn wcscpy
+and
+.Fn wcsncpy
+functions were ported from
+.Nx
+and first appeared in
+.Ox 3.8 .
+.Sh CAVEATS
+Using the functions
+.Fn wcscpy
+and
+.Fn wcsncpy
+is very error-prone with respect to buffer overflows;
+see the EXAMPLES section in
+.Xr strcpy 3
+for correct usage.
+Using
+.Xr wcslcpy 3
+is a better choice in most cases.
