# openSync method

RandomAccessFile openSync ({FileMode mode: FileMode.read })

Synchronously open the file for random access operations. The result is a RandomAccessFile on which random access operations can be performed. Opened RandomAccessFiles must be closed using the RandomAccessFile.close method.

See open for information on the `mode` argument.

Throws a FileSystemException if the operation fails.
