LocalMon: Sample Port Monitor Server DLL

SUMMARY

A port monitor DLL is a user-mode DLL that is responsible for providing a communications path between the user-mode print spooler and the kernel-mode port drivers that access I/O port hardware. Please refer to the DDK documentation for further information about print monitors.

This sample runs on the x86 platform and the code is 64-bit compliant.

BUILDING THE SAMPLE

To build the sample, run build from this directory. Once built, the sample will produce the binary DDKLocalmon.dll.

The INF file monitor.inf is used for installing the port monitor. Both the port monitor DLL and the port monitor’s user interface DLL are installed using the monitor.inf file.
