TestSRQ

Name

TestSRQ -- query state of SRQ bus line

Synopsis

#include <gpib/ib.h>

void TestSRQ(int board_desc, short *result);

Description

TestSRQ() checks the state of the SRQ bus line and writes its state to the location specified by result. A '1' indicates the SRQ line is asserted, and a '0' indicates the line is not asserted.

Some boards lack the capability to report the status of the SRQ line. In such a case, an ECAP error is returned in iberr.
