AllSpoll
Purpose
Serial poll all devices.
Format
C
|
void AllSpoll (int boardID, const Addr4882_t *addrlist, short *resultlist)
|
Visual Basic
|
CALL AllSpoll (boardID%, addrlist%(), resultlist%())
|
Input
|
boardID
|
The interface number |
|
addrlist
|
A list of device addresses terminated by NOADDR
|
Output
|
resultlist
|
A list of serial poll response bytes corresponding to device addresses in addrlist
|
Description
AllSpoll serial polls all of the devices described by addrlist. It stores the poll responses in resultlist and the number of responses in Ibcnt. For more information about serial polling, refer to the Serial Polling Overview.
Possible Errors
|
EABO
|
One of the devices timed out instead of responding to the serial poll; Ibcnt contains the index of the timed-out device. |
|
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. |
|
EOIP
