 Okay that shout not a problem.

calculation:

  From the MSDN (http://msdn2.microsoft.com/en-us/library/ms795740.aspx) 
the next buffer
 offset must be greater than zero and must fall on a ULONG boundary.

 EaBufferEnd->EaNameLength+EaBufferEnd->EaValueLength + 9:

  The Length of the rest of the buffer must lesser equal to the size of 
the Name + Value + BYTE_ALIGN(sizeof(FILE_FULL_EA_INFORMATION)).
