-
-Current WARNINGS
-
- WARNING- If yaffs is unmounted then most of yaffs' functions return ENODIR.
- But some function return EBADF instead.
- Functions which return ENOTDIR: open, close, access, unlink, lseek, write, read
-
- Functions which return ENOENT: access, stat
-
-
-
- WARNING-the function yaffs_open does not check the mode passed to it.
- This means that yaffs open does not return EINVAL if a bad mode is passed to it.
- However this causes the error EEXIST to happen instead, because both O_CREAT and O_EXCL flags are set.
-
- WARNING- yaffs_open will work with either of the two mode set to 255.
- However there are only 4 or 5 flags that can be set for each of the modes.
- This means that the programmer may not be setting the flags properly.
-
- WARNING- When mounting a non-existing mount point the error ENODEV is returned.
- The quick tests have been altered to accommodate this error code.
- With standard access function in linux the error returned is ENOENT.
