class socket_descr :?blocking:bool -> ?start_pos_in:int -> ?start_pos_out:int -> ?fd_style:Netsys.fd_style -> Unix.file_descr ->raw_io_channel
Creates a raw_io_channel for the passed socket descriptor, which must
be open for reading and writing, and not yet shut down in either
direction. The raw_io_channel is used to represent a bidirectional
channel: close_out shuts the socket down for sending, close_in
shuts the socket down for reading, and when both directions are down,
the descriptor is closed.
The pos_in and pos_out methods returns logical positions.
This class supports sockets and Win32 named pipes. Note, however, that for Win32 named pipes it is not possible to shut down only one direction of the bidirectional data channel.
start_pos_in : The position to which pos_in is initialized when
the channel is created, by default 0start_pos_out : The position to which pos_out is initialized when
the channel is created, by default 0fd_style : The descriptor style. If omitted, it is automatically
determined if possible.
