This is platform-depending limitation. It can be be changed in future. In addition, there are other causes of writing not all data (see `man 2 write`). > Also, it might be nice to add a note on top, that this module is for 'low > level' IO interface, and that it is recommended to use regular file type for > typical file operations (not io.FileIO) to avoid necessity of dealing > limitations such as the one mentioned. This is not true for the module overall. And this is already documented for io.RawIOBase: """ Raw binary I/O typically provides low-level access to an underlying OS device or API, and does not try to encapsulate it in high-level primitives (this is left to Buffered I/O and Text I/O, described later in this page).
