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%())

Interactive Control (Usage Notes)

AllSpoll addrlist

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	Asynchronous I/O is in progress.
