GPIB Programming Techniques
/* Use FindRQS to find a device that requested service. */
FindRQS ( 0, AddrList, &SerialPollResponse );

Example 2

This example illustrates the use of AllSpoll to serial poll three devices.
void GetAllSerialPollResponses ( Addr4882_t AddrList[],
short ResponseList[] )
{
int WaitResult;
WaitSRQ (0, &WaitResult);
if ( WaitResult ) {
printf ( "SRQ is asserted.\n" );
/* Use Allspoll to serial poll all the devices at once.*/
AllSpoll ( 0, AddrList, ResponseList );
if (!(ibsta & ERR))
for ( i = 0; AddrList[i] != NOADDR; i++ )
printf("Device at pad %x returned byte %x.\n",
}
}
}
return;
}
