IO::Buffer#each_byte

each_byte([offset, [count]]) {|byte| ...} → self

each_byte([offset, [count]]) → enumerator

static VALUE
io_buffer_each_byte(int argc, VALUE *argv, VALUE self)
{
    RETURN_ENUMERATOR_KW(self, argc, argv, RB_NO_KEYWORDS);

    struct io_buffer_each_arguments arguments = {
        .self = self,
        .argc = argc,
        .argv = argv,
    };

    rb_io_buffer_lock(self);
    return rb_ensure(io_buffer_each_byte_locked, (VALUE)&arguments, rb_io_buffer_locked_ensure, self);
}

Iterates over the buffer, yielding each byte starting from offset.

If count is given, only count bytes will be yielded.

Example

IO::Buffer.for("Hello World").each_byte(2, 2) do |offset, byte|
  puts "#{offset}: #{byte}"
end
# 2: 108
# 3: 108
