Just read the whole file, prepend and then write the whole file. In any case I do not know a way to actually prepend bytes to the file: if you seek to the end of file (or open it in append mode) and start writing to it you get appending. If you seek to the start and start writing you will just overwrite first bytes. So programming languages do not have “prepending” abstraction because it is not supported by the OS and thus is going to either cost very much or have problems like loosing data on crashes. > > Thank you > Niva > > -- > -- > You received this message from the "vim_use" maillist. > Do not top-post!
