There is no "NDIS way" for an NDIS driver to (directly) write to a
file. The NdisOpenFile() etc. is only there for read-only purposes.
One should usually use NdisWriteErrorLogEntry() to write log entries.
The 'ErrorCode' does *not* need to be an actual error code, i.e. it
can also be a warning or an informational entry. More, although tbe
docs say about the 'ErrorCode' that it "Specifies the NDIS_STATUS_XXX
code describing the I/O error", it does not actually need to be an
NDIS_STATUS_XXX code. Instead, you can define your own codes. Then you
can add a message file to your driver (compiled with MC - the message
compiler), which contains messages for each code that you define. That
will enable the Event Viewer to display your codes along with a
meaningful message.
For more information see "Logging Errors" in the DDK docs:
http://msdn.microsoft.com/library/en-us/kmarch/hh/kmarch/other_92jr.asp
-> "Defining Custom Error Types"
Note that I have never used NdisWriteEventLogEntry() ("event"), which
may also be an option for you.
