-.SH DESCRIPTION
-The
-.BR mempcpy ()
-function is nearly identical to the
-.BR memcpy (3)
-function.
-It copies
-.I n
-bytes from the object beginning at
-.I src
-into the object pointed to by
-.IR dest .
-But instead of returning the value of
-.I dest
-it returns a pointer to the byte following the last written byte.
-.P
-This function is useful in situations where a number of objects
-shall be copied to consecutive memory positions.
-.P
-The
-.BR wmempcpy ()
-function is identical but takes
-.I wchar_t
-type arguments and copies
-.I n
-wide characters.
-.SH RETURN VALUE
-.I dest
-+
-.IR n .
