Common Parameters
— Reserved (2 bytes).
• data associated with the option entries (variable length).
If the parameter is declared as a simple byte array, it must be large
enough to contain 4 bytes for the first two fixed-length fields, 8 bytes for
each option entry, plus the actual data. That is:
4 + 8 * numentries + datalength
NOTE Use of certain opt parameter options may result in the loss of
portability between different Hewlett-Packard systems.
