class buffered_raw_out_channel :?buffer_size:int -> ?pass_through:int -> raw_out_channel ->raw_out_channel
This class adds a buffer to the underlying raw_out_channel.
buffer_size : The size of the buffer, by default 4096.pass_through : If the write request has at least this size,
and the buffer is currently empty, the buffer will be bypassed.
Defaults to max_int, i.e. it is off.
