- * Some notes about how inet (currently only tcp) works on OSE.
- * The driver uses OSE signals to communicate with the one_inet
- * process. Because of the difference in how signals and file descriptors
- * work the whole select/deselect mechanic is very different.
- * In ose when a sock_select is done a function is called. That function
- * notes the changes that the driver want to do, but does not act on it.
- * later when the function returns the new desired state is compared
- * to the previous state and the apprioriate actions are taken. The action
- * is usually to either request more data from the stack or stop requesting
- * data.
- *
- * One thing to note is that the driver never does select/deselect. It always
- * listens for the signals. Flow of data is regulated by sending or not sending
- * signals to the ose inet process.
- *
- * The interesting functions to look at are:
- * * inet_driver_select : called when sock_select is called
- * * tcp_inet_ose_dispatch_signal : checks state changes and sends new signals
- * * tcp_inet_drv_output_ose : ready output callback, reads signals and calls
- * dispatch_signal
- * * tcp_inet_drv_input_ose : ready input callback.

- * Changes the name of an existing file or directory, from src to dst.
- * If src and dst refer to the same file or directory, does nothing
- * and returns success. Otherwise if dst already exists, it will be
- * deleted and replaced by src subject to the following conditions:
- * If src is a directory, dst may be an empty directory.
- * If src is a file, dst may be a file.
- * In any other situation where dst already exists, the rename will
- * fail.
- *
- * Results:
- * If the directory was successfully created, returns 1.
- * Otherwise the return value is 0 and errno is set to
- * indicate the error. Some possible values for errno are:
- *
- * EACCES: src or dst parent directory can't be read and/or written.
- * EEXIST: dst is a non-empty directory.
- * EINVAL: src is a root directory or dst is a subdirectory of src.
- * EISDIR: dst is a directory, but src is not.
- * ENOENT: src doesn't exist, or src or dst is "".
- * ENOTDIR: src is a directory, but dst is not.
- * EXDEV: src and dst are on different filesystems.
- *
- * Side effects:
- * The implementation of rename may allow cross-filesystem renames,
- * but the caller should be prepared to emulate it with copy and
- * delete if errno is EXDEV.
