A method is described which allows a user program to dynamically specify a minimum device error severity which is to be reported, and which provides detailed device error information. User programs typically do not have knowledge of where program output is directed. The output may be in a file, or it may go to a device. Such programs are usually not prepared to handle device errors if they should occur. On the other hand, certain user programs may have the job of servicing a device. These types of programs would certainly be interested in device errors. The details of this method are described for the UNIX* operating system running as a virtual machine on the Virtual Resource Manager (VRM) control program. The VRM control program is similar in concept to the IBM VM/370 control program.
