PPollUnconfig
Purpose
Unconfigure devices for parallel polls.
Format
C
|
void PPollUnconfig (int boardID, const Addr4882_t *addrlist)
|
Visual Basic
|
CALL PPollUnconfig (boardID%, addrlist%())
|
Input
|
boardID
|
The interface number |
|
addrlist
|
A list of device addresses that is terminated by NOADDR
|
Description
PPollUnconfig unconfigures all the devices described by addrlist for parallel polls. If addrlist contains only the constant NOADDR, the Parallel Poll Unconfigure (PPU) GPIB message is sent to all GPIB devices. The devices unconfigured by this function do not participate in subsequent parallel polls.
For more information about parallel polling, refer to the Parallel Polling Overview.
Possible Errors
|
EARG
|
An invalid address appears in addrlist; Ibcnt is the index of the first invalid address in the addrlist array. |
|
EBUS
|
No devices are connected to the GPIB. |
|
ECIC
|
The interface is not the Controller-In-Charge; see SendIFC. |
|
EDVR
|
The NI-488.2 driver is either configured incorrectly or is not properly installed. |
|
EHDL
|
boardID is out of range. |
|
ELCK
|
The requested operation could not be performed because of an existing lock by another process. |
|
ENEB
|
The interface is not installed or is not properly configured. |
|
