| rb_io_buffer_t rb_io::wbuf |
| VALUE rb_io::write_lock |
This is a Ruby level mutex.
It avoids multiple threads to write to an IO at once; helps for instance rb_io_puts() to ensure newlines right next to its arguments.
This of course doesn't help inter-process IO interleaves, though.
| rb_econv_t * rb_io::writeconv |
Encoding converter used when writing to this IO.
Definition at line 211 of file io.h.
Referenced by rb_io_binmode().
| VALUE rb_io::writeconv_asciicompat |
This is, when set, an instance of rb_cString which holds the "common" encoding.
Write conversion can convert strings twice... In case conversion from encoding X to encoding Y does not exist, Ruby finds an encoding Z that bridges the two, so that X to Z to Y conversion happens.
| int rb_io::writeconv_initialized |
Whether rb_io_t::writeconv is already set up.
| int rb_io::writeconv_pre_ecflags |
Value of ::rb_io_t::rb_io_enc_t::ecflags stored right before initialising rb_io_t::writeconv.

| VALUE rb_io::writeconv_pre_ecopts |
