Hello,

from your error description alone it's hard to tell what goes wrong. Can you perhaps send us a test program (and run script) where the loss of file content can be observed? The file content should get flushed when closing the file via the 'close()' function. Does your test program do that?

Regards,
Christian

Dear Genode,

  I'm having some trouble with the File I/O.

  I implemented the File I/O test program to test the Genode. And then, I had 
experienced a loss of file contents.
  The root cause is my mistake that I doesn't call the fsync function at end of 
writing. But I can't understand that the file contents is never flushed, even if 
the application doesn't not call fsync. I assume that the file system of genode 
doesn't not using the background flush.
  Is it correct? And if it is right, could you tell me why genode doesn't not 
provide the function of background flush?

Best,
Kim, Youn-woo.
