Detailed Description
- Note:
- These functions must be called prior to the initialisation of the device structures. That means before any call to
vpb_open()
, vpb_get_num_cards()
, or vpb_get_ports_per_card()
is made.
- Exceptions:
-
| VpbException | will be thrown if they are called after device initialisation has taken place. |
If you really must change them after that, you may call
vpb_close()
, (with no arguments) to close all ports and release the existing device structures, then call them before re-opening the desired ports.
