Parameters

client Pointer to the client buffer.
block Command block.
oldpath The file or directory path to be renamed. Length must be less than FS_MAX_ARGPATH_SIZE.
newpath New file or directory path. Length must be less than FS_MAX_ARGPATH_SIZE.
errHandling Auto error handling flag. Only indicated errors are returned.
asyncParams (Async API only) Notification parameters for an asynchronous call.

Return Values

Sync API : Return values / Async API: Callback return values

FS_STATUS_OK Successfully completed.
FS_STATUS_CANCELED The command was canceled.
FS_STATUS_NOT_FOUND Target not found.
FS_STATUS_NOT_DIR Specified path includes a file entry as directory.
FS_STATUS_PERMISSION_ERROR The caller does not have correct access permission.
FS_STATUS_EXISTS New name already exists but has a different inode type.
FS_STATUS_ALREADY_OPEN There is one or more open file or directory in source path or destination path.
FS_STATUS_UNSUPPORTED_CMD Associated file system does not support this function.
FS_STATUS_STORAGE_FULL Data space cannot be allocated to update directory tree.
FS_STATUS_JOURNAL_FULL Journaling space is full and new journaling block cannot be allocated.
FS_STATUS_MEDIA_NOT_READY (Only for manually mounted devices) Media is not present.
FS_STATUS_MEDIA_ERROR (Only for manually mounted devices) Media is in some inaccessible condition.
FS_STATUS_DATA_CORRUPTED (Only for manually mounted devices) The data is corrupted beyond repair. The volume needs format.
FS_STATUS_WRITE_PROTECTED (Only for manually mounted devices) Media is write protected.

Async API: Immediate return values

FS_STATUS_OK Successfully issued request.
FS_STATUS_FATAL_ERROR The argument is invalid.

Description

Renames the file or directory entry designated by oldpath to newpath. It only lets filesystem changes its metadata without transferring data itself. oldpath and newpath must be on the same mount point.

Both a sync and async style API are provided. To use the async API, set the user callback and parameters in asyncParams. For more information, see FSAsyncParams.
