[ECOS] JFFS2 lseek

[eibach@gdsys.de]

Hello,

The The Single UNIX ­ Specification, Version 2 states the following about the lseek function:

"The lseek() function will allow the file offset to be set beyond the end of the existing data in the file. If data is later written at this point, subsequent reads of data in the gap will return bytes with the value 0 until data is actually written into the gap."

The code in jffs2_fo_lseek contains the following:

// Check that pos is still within current file size, or at the
// very end.
if (pos < 0 || pos > node->i_size)
  return EINVAL;

So it seems lseek() does not allow to set the offset beyond the current end of file. Is that correct or am I getting something wrong?
Any suggestions how this could be fixed?

Regards,
Dirk
