NAME

       TestSys - perform self-test queries on devices

SYNOPSIS

       #include <gpib/ib.h>

       void TestSys(int board_desc, const Addr4882_t addressList[], short results[]);

DESCRIPTION

       TestSys() sends the '*TST?' message to all the devices in the addressList array, then reads their
       responses into the results array. This will cause devices that conform to the IEEE 488.2 standard to
       perform a self-test and respond with a zero on success. A non-zero response indicates an error during the
       self-test.

       The number of devices which responded with nonzero values from their self-tests is returned in ibcnt,
       ibcntl. If a device fails to respond to the *TST? query, an error will be flagged in ibsta (this is
       different than NI's documented behaviour which is broken).
