At times, fixed-length uninterpreted
data needs to be passed among machines. This data is called opaque
.
Opaque data is declared as follows.
opaque identifier[n];
In this declaration, the constant n is the static number of bytes necessary to contain the opaque data. The n bytes are followed by enough (0 to 3) residual zero bytes r to make the total byte count of the opaque object a multiple of four.
