Status: UNCONFIRMED
Severity: normal

proposed patch to fix this defect
The fcntl function does not handle F_GETFL, F_SETFL at all.
Furthermore, the result of F_DUPFL is not returned.
Note, the ustl uses fcntl() to set a file to non-blocking,
see fstream::set_nonblock().
The attached patch for "ecos/packages/io/fileio/current/src/io.cxx"
adds the necessary implementation for this function codes to fcntl().
Furthermore, it enables the ioctl function code FIONBIO to change
the file flag O_NONBLOCK accordingly.
