Samuel Williams 18e55fc1e1 Hide most of the implementation of struct rb_io. (#6511) ... * Add rb_io_path and rb_io_open_descriptor. * Use rb_io_open_descriptor to create PTY objects * Rename FMODE_PREP -> FMODE_EXTERNAL and expose it FMODE_PREP I believe refers to the concept of a "pre-prepared" file, but FMODE_EXTERNAL is clearer about what the file descriptor represents and aligns with language in the IO::Buffer module. * Ensure that rb_io_open_descriptor closes the FD if it fails If FMODE_EXTERNAL is not set, then it's guaranteed that Ruby will be responsible for closing your file, eventually, if you pass it to rb_io_open_descriptor, even if it raises an exception. * Rename IS_EXTERNAL_FD -> RUBY_IO_EXTERNAL_P * Expose `rb_io_closed_p`. * Add `rb_io_mode` to get IO mode. --------- Co-authored-by: KJ Tsanaktsidis <ktsanaktsidis@zendesk.com>		2023-05-30 10:02:40 +09:00
