GetDeviceDriverFileNameW(
LPVOID ImageBase,
LPWSTR lpFilename,
DWORD nSize

/*++
Routine Description:
This function retrieves the full pathname of the executable file
from which the specified module was loaded. The function copies the
null-terminated filename into the buffer pointed to by the
lpFilename parameter.
Routine Description:
ImageBase - Identifies the driver whose executable file name is being
requested.
lpFilename - Points to the buffer that is to receive the filename.
nSize - Specifies the maximum number of characters to copy. If the
filename is longer than the maximum number of characters
specified by the nSize parameter, it is truncated.
Return Value:
The return value specifies the actual length of the string copied to
the buffer. A return value of zero indicates an error and extended
error status is available using the GetLastError function.
Arguments:
