Software & Application Miscellaneous: ZwReadFile?

• anonymous / 205 / Sat, 20 Jun 2009 12:07:00 GMT / Comments (1)
• Hi.
  
  I could be able to read the contents from the file from the kernel mode...
  It reads in ASCII format ...
  How to make it read in the same format as it is in the file?
  
  The code I have used is..
  
  ntStatus = ZwCreateFile( &NtFileHandle,
  SYNCHRONIZE | FILE_READ_DATA, // I have tried
  with GENERIC_READ also...
  &ObjectAttributes,
  &IoStatus,
  NULL, // alloc size
  =none
  FILE_ATTRIBUTE_NORMAL,
  FILE_SHARE_READ,
  FILE_OPEN,
  FILE_SYNCHRONOUS_IO_NONALERT |
  FILE_NON_DIRECTORY_FILE,
  NULL, // eabuffer
  0 ); // ealength
  
  ntStatus = ZwReadFile( NtFileHandle,
  NULL,
  NULL,
  NULL,
  &IoStatus,
  FileImage, // Read Buffer
  LengthOfFile,
  NULL,
  NULL );
  
  where to make the change to read it in AlphaNumeric mode... ( ie I want the
  content of the Read Buffer[FileImage] in Alphanumeric format)?
  
  Regards,
  Anand.

• 1. Hello,
     
     You mean alpha numeric mode? You mean as you would in fopen("filename.txt",
     "rt") ?
     
     After you read into the buffer, you can parse into lines by looking for \n
     or \r\n combinations.
