Detailed Description

template<class _Base>
class BazisLib::DDK::_DirectFile< _Base >

Represents a file that is read/written by sending IRP_MJ_READ/IRP_MJ_WRITE IRPs to FS driver.

The experimental DirectFile class allows accessing NT files by sending IRP_MJ_READ/IRP_MJ_WRITE IRPs directly to filesystem driver. This allows bypassing restrictions implied by ZwReadFile()/ ZwWriteFile() routines.

Remarks:

Note that all operations except reading and writing are performed using the file handle and may inherit some restrictions implied by object manager & IO manager.
