/* OPERATIONS are numbered APDU_OPx, where each is a unique integer. Further,
APDU_UNKNOWN is used as a tag different than any valid operation.
ERRORS are numbered ERROR_xyz, where each is a unique integer.
ERROR_MISTYPED is used to signal an argument error to an operation.
Further, ERROR_UNKNOWN is used as a tag to indicate that the operation
succeeded.
Finally, note that rox -> rox_args is updated in place by these routines.
If the routine returns ERROR_UNKNOWN, then rox_args contains the results
of the operation. If the routine returns ERROR_MISTYPED, then rox_args is
untouched. Otherwise, if the routine returns any other value, then
rox_args contains the parameters of the error which occurred. Obviously,
each routine calls ROXFREE prior to setting rox_args to a new value.
