The benefits of this are: 1. Rounds out the stream ioctl function, which already includes flush, seek and poll (among other things). 2. Makes calling mp_stream_close() on an object slightly more efficient because it now no longer needs to lookup the close method and call it, rather it just delegates straight to the ioctl function (if it exists). 3. Reduces code size and allows future types that implement the stream protocol to be smaller because they don't need a dedicated close method. Code size reduction is around 200 bytes smaller for x86 archs and around 30 bytes smaller for the bare-metal archs. extmod/vfs_fat_file: Implement SEEK_CUR for non-zero offset. 2018-03-23T14:19:56+00:00 Ayke van Laethem aykevanlaethem@gmail.com 2017-12-19T22:47:07+00:00 urn:sha1:fa55b15ac6a15be0c11123753760324547518a18 CPython doesn't allow SEEK_CUR with non-zero offset for files in text mode, and uPy inherited this behaviour for both text and binary files. It makes sense to provide full support for SEEK_CUR of binary-mode files in uPy, and to do this in a minimal way means also allowing to use SEEK_CUR with non-zero offsets on text-mode files. That seems to be a fair compromise.
