The &func function copies
.arg length
characters from the buffer pointed to by
.arg src
to the buffer pointed to by
.arg dst.
Copying of overlapping objects will take place properly.
See the
.kw memcpy
function to copy objects that do not overlap.

The &wfunc wide-character function is identical to &func except that it
operates on characters of
.kw wchar_t
type.
The argument
.arg length
is interpreted to mean the number of wide characters.

:cmt. The &ufunc Unicode function is identical to &func except that it
:cmt. operates on 16-bit Unicode character strings.
:cmt. The argument
:cmt. .arg length
:cmt. is interpreted to mean the number of Unicode characters.
