- * TrustedBSD implementation of cap_copy_ext()/cap_copy_int()
- *
- * These are largely nops currently, because our internal format is contiguous.
- * We just copy our representation out, and do some minumum validations on
- * external data.
- *
- * XXX: we cannot detect cap being invalid. If it is, the program will probably
