[PATCH] kernel32: Implement K32EnumDeviceDrivers and K32GetDeviceDriverBaseNameA (pt. 2)

[Anthony Lauzon]

I noticed my submission yesterday was a little undercooked and since I have
spent some more time on it, I thought I'd try to submit a (hopefully)
proper patch to the list.  This is a rough implementation of
K32EnumDeviceDrivers and K32GetDeviceDriverBaseNameA.

This is enumerating the modules loaded in the current process, it
doesn't have anything to do with device drivers. What problem are you
trying to solve?

I followed the ReactOS code and the documentation from Microsoft for the
EnumDeviceDrivers function for this code.  I'm attaching a link to the
stack trace from the program I'm trying to run.  It's the Creative E-MU
Emulator X3.  The error is an invalid floating point for 32-bit code error.​
