 possible to use a file descriptor opened in raw mode:

+
+== Name
+
+ranch_transport - behaviour for transport modules
+
+== Description
+
+The `ranch_transport` behaviour defines the interface used
+by Ranch transports.
+
+== Types
+
+=== sendfile_opts() = [{chunk_size, non_neg_integer()}]
+
+Options used by the sendfile function and callbacks.
+
+Allows configuring the chunk size, in bytes. Defaults to 8191 bytes.
+
+== Callbacks
+
+=== accept(LSocket, Timeout) -> {ok, CSocket} | {error, closed | timeout | atom()}
+
+LSocket = CSocket = any():: Listening socket.
+Timeout = timeout():: Accept timeout.
+
+Accept a connection on the given listening socket.
+
+The `accept_ack` callback will be used to initialize the socket
+after accepting the connection. This is most useful when the
+transport is not raw TCP, like with SSL for example.
+
+=== accept_ack(CSocket, Timeout) -> ok
+
+CSocket = any():: Socket for this connection.
+Timeout = timeout():: Ack timeout.
+
+Perform post-accept initialization of the connection.
+
+This function will be called by connection processes
+before performing any socket operation. It allows
+transports that require extra initialization to perform
+their task and make the socket ready to use.
+
+=== close(Socket) -> ok
+
+Socket = any():: Socket opened with listen/1 or accept/2.
+
+Close the given socket.
+
+=== controlling_process(Socket, Pid) -> ok | {error, closed | not_owner | atom()}
+
+Socket = any():: Socket opened with listen/1 or accept/2.
+Pid = pid():: Pid of the new owner of the socket.
+
+Change the controlling process for the given socket.
+
+The controlling process is the process that is allowed to
+perform operations on the socket, and that will receive
+messages from the socket when active mode is used. When
+the controlling process dies, the socket is closed.
+
+=== listen(TransOpts) -> {ok, LSocket} | {error, atom()}
+
+TransOpts = any():: Transport options.
+LSocket = any():: Listening socket.
+
+Listen for connections on the given port.
+
+The port is given as part of the transport options under
+the key `port`. Any other option is transport dependent.
+
+The socket returned by this call can then be used to
+accept connections. It is not possible to send or receive
+data from the listening socket.
+
+=== messages() -> {OK, Closed, Error}
+
+OK = Closed = Error = atom():: Tuple names.
+
+Return the atoms used to identify messages sent in active mode.
+
+=== name() -> Name
+
+Name = atom():: Transport module name.
+
+Return the name of the transport.
+
+=== peername(CSocket) -> {ok, {IP, Port}} | {error, atom()}
+
+CSocket = any():: Socket for this connection.
+IP = inet:ip_address():: IP of the remote endpoint.
+Port = inet:port_number():: Port of the remote endpoint.
+
+Return the IP and port of the remote endpoint.
+
+=== recv(CSocket, Length, Timeout) -> {ok, Packet} | {error, closed | timeout | atom()}
+
+CSocket = any():: Socket for this connection.
+Length = non_neg_integer():: Requested length.
+Timeout = timeout():: Receive timeout.
+Packet = iodata() | any():: Data received.
+
+Receive data from the given socket when in passive mode.
+
+Trying to receive data from a socket that is in active mode
+will return an error.
+
+A length of 0 will return any data available on the socket.
+
+While it is possible to use the timeout value `infinity`,
+this is highly discouraged as this could cause your process
+to get stuck waiting for data that will never come. This may
+happen when a socket becomes half-open due to a crash of the
+remote endpoint. Wi-Fi going down is another common culprit
+of this issue.
+
+=== send(CSocket, Packet) -> ok | {error, atom()}
+
+CSocket = any():: Socket for this connection.
+Packet = iodata():: Data to be sent.
+
+Send data to the given socket.
+
+=== sendfile(CSocket, File) -> sendfile(CSocket, File, 0, 0, [])
+
+Alias of `ranch_transport:sendfile/5`.
+
+=== sendfile(CSocket, File, Offset, Bytes) -> sendfile(CSocket, File, Offset, Bytes, [])
+
+Alias of `ranch_transport:sendfile/5`.
+
+=== sendfile(CSocket, File, Offset, Bytes, SfOpts) -> {ok, SentBytes} | {error, atom()}
+
+CSocket = any():: Socket for this connection.
+File = file:filename_all() | file:fd():: Filename or file descriptor for the file to be sent.
+Offset = non_neg_integer():: Begin sending at this position in the file.
+Bytes = non_neg_integer():: Send this many bytes.
+SentBytes = non_neg_integer():: This many bytes were sent.
+SfOpts = sendfile_opts():: Sendfile options.
+
+Send data from a file to the given socket.
+
+The file may be sent full or in parts, and may be specified
+by its filename or by an already open file descriptor.
+
+Transports that manipulate TCP directly may use the
+`file:sendfile/{2,4,5}` function, which calls the sendfile
+syscall where applicable (on Linux, for example). Other
+transports can use the `sendfile/6` function exported from
+this module.
+
+=== setopts(CSocket, SockOpts) -> ok | {error, atom()}
+
+CSocket = any():: Socket for this connection.
+SockOpts = any():: Socket options.
+
+Change options for the given socket.
+
+This is mainly useful for switching to active or passive mode
+or to set protocol-specific options.
+
+=== shutdown(CSocket, How) -> ok | {error, atom()}
+
+CSocket = any():: Socket for this connection.
+How = read | write | read_write:: Which side(s) of the socket to close.
+
+Immediately close the socket in one or two directions.
+
+=== sockname(Socket) -> {ok, {IP, Port}} | {error, atom()}
+
+Socket = any():: Socket opened with listen/1 or accept/2.
+IP = inet:ip_address():: IP of the local endpoint.
+Port = inet:port_number():: Port of the local endpoint.
+
+Return the IP and port of the local endpoint.
+
+== Exports
+
+=== sendfile(Transport, CSocket, File, Offset, Bytes, SfOpts) -> {ok, SentBytes} | {error, atom()}
+
+Transport = module():: Transport module for this socket.
+CSocket = any():: Socket for this connection.
+File = file:filename_all() | file:fd():: Filename or file descriptor for the file to be sent.
+Offset = non_neg_integer():: Begin sending at this position in the file.
+Bytes = non_neg_integer():: Send this many bytes.
+SentBytes = non_neg_integer():: This many bytes were sent.
+SfOpts = sendfile_opts():: Sendfile options.
+
+Send data from a file to the given socket.
+
+This function emulates the function `file:sendfile/{2,4,5}`
+and may be used when transports are not manipulating TCP
+directly.

-ranch
-=====
-
-The `ranch` module provides functions for starting and
-manipulating Ranch listeners.
-
-Types
------
-
-### max_conns() = non_neg_integer() | infinity
-
-> Maximum number of connections allowed on this listener.
->
-> This is a soft limit. The actual number of connections
-> might be slightly above the limit due to concurrency
-> when accepting new connections. Some connections may
-> also be removed from this count explicitly by the user
-> code.
-
-### opt() = {ack_timeout, timeout()}
-	| {connection_type, worker | supervisor}
-	| {max_connections, max_conns()}
-	| {shutdown, timeout() | brutal_kill}
-	| {socket, any()}
-
-> Ranch-specific transport options.
->
-> These options are not passed on to the transports.
-> They are used by Ranch while setting up the listeners.
-
-### ref() = any()
-
-> Unique name used to refer to a listener.
-
-Exports
--------
-
-### accept_ack(Ref) -> ok
-
-> Types:
->  *  Ref = ref()
->
-> Acknowledge that the connection is accepted.
->
-> This function MUST be used by a connection process to inform
-> Ranch that it initialized properly and let it perform any
-> additional operations before the socket can be safely used.
-
-### child_spec(Ref, NbAcceptors, Transport, TransOpts, Protocol, ProtoOpts)
-	-> supervisor:child_spec()
-
-> Types:
->  *  Ref = ref()
->  *  NbAcceptors = non_neg_integer()
->  *  Transport = module()
->  *  TransOpts = any()
->  *  Protocol = module()
->  *  ProtoOpts = any()
->
-> Return child specifications for a new listener.
->
-> This function can be used to embed a listener directly
-> in an application instead of letting Ranch handle it.
-
-### get_max_connections(Ref) -> MaxConns
-
-> Types:
->  *  Ref = ref()
->  *  MaxConns = max_conns()
->
-> Return the max number of connections allowed for the given listener.
-
-### get_port(Ref) -> Port
-
-> Types:
->  *  Ref = ref()
->  *  Port = inet:port_number()
->
-> Return the port for the given listener.
-
-### get_protocol_options(Ref) -> ProtoOpts
-
-> Types:
->  *  Ref = ref()
->  *  ProtoOpts = any()
->
-> Return the protocol options set for the given listener.
-
-### remove_connection(Ref) -> ok
-
-> Types:
->  *  Ref = ref()
->
-> Do not count this connection when limiting the number of connections.
->
-> You can use this function for long-running connection processes
-> which spend most of their time idling rather than consuming
-> resources. This allows Ranch to accept a lot more connections
-> without sacrificing the latency of the system.
->
-> This function may only be called from a connection process.
-
-### set_max_connections(Ref, MaxConns) -> ok
-
-> Types:
->  *  Ref = ref()
->  *  MaxConns = max_conns()
->
-> Set the max number of connections for the given listener.
->
-> The change will be applied immediately. If the new value is
-> smaller than the previous one, Ranch will not kill the extra
-> connections, but will wait for them to terminate properly.
-
-### set_protocol_options(Ref, ProtoOpts) -> ok
-
-> Types:
->  *  Ref = ref()
->  *  ProtoOpts = any()
->
-> Set the protocol options for the given listener.
->
-> The change will be applied immediately for all new connections.
-> Old connections will not receive the new options.
-
-### start_listener(Ref, NbAcceptors, Transport, TransOpts, Protocol, ProtoOpts)
-	-> {ok, pid()} | {error, badarg}
-
-> Types:
->  *  Ref = ref()
->  *  NbAcceptors = non_neg_integer()
->  *  Transport = module()
->  *  TransOpts = any()
->  *  Protocol = module()
->  *  ProtoOpts = any()
->
-> Start listening for connections using the given transport
-> and protocol. Returns the pid for this listener's supervisor.
->
-> There are five additional transport options that apply
-> regardless of transport. They allow configuring how the
-> connections are supervised, rate limited and allow using
-> an already open listening socket.
->
-> The `ack_timeout` option defines how long post-accept socket
-> initialization should take at a maximum. It defaults to `5000`.
->
-> The `connection_type` option defines the type of process
-> that will handle the connection. It can be either `worker`
-> or `supervisor`. It defaults to `worker`.
->
-> The `max_connections` option determines how many active
-> connections are allowed before Ranch starts throttling
-> the accept rate. This is a soft limit. It defaults to `1024`.
-> Using the value `infinity` will disable this functionality
-> entirely.
->
-> The `shutdown` option determines the policy used with
-> regards to connection processes when shutting down the listener.
-> It can be either a positive integer indicating the max number
-> of ms the supervisor will wait before forcibly killing the
-> children, or the atom `brutal_kill`. It defaults to `5000`.
->
-> The `socket` option allow passing an already open listening
-> socket. In this case, Ranch will not call `Transport:listen/1`
-> and so none of the transport specific options apply.
-
-### stop_listener(Ref) -> ok | {error, not_found}
-
-> Types:
->  *  Ref = ref()
->
-> Stop the given listener.
->
-> The listener is stopped gracefully, first by closing the
-> listening port, then by stopping the connection processes.
-> These processes are stopped according to the `shutdown`
-> transport option, which may be set to brutally kill all
-> connection processes or give them some time to stop properly.
->
-> This function does not return until the listener is
-> completely stopped.

-ranch_transport
-===============
-
-The `ranch_transport` behaviour defines the interface used
-by Ranch transports.
-
-Types
------
-
-### sendfile_opts() = [{chunk_size, non_neg_integer()}]
-
-> Options used by the sendfile function and callbacks.
->
-> Allows configuring the chunk size, in bytes. Defaults to 8191 bytes.
-
-Callbacks
----------
-
-### accept(LSocket, Timeout)
-	-> {ok, CSocket} | {error, closed | timeout | atom()}
-
-> Types:
->  *  LSocket = CSocket = any()
->  *  Timeout = timeout()
->
-> Accept a connection on the given listening socket.
->
-> The `accept_ack` callback will be used to initialize the socket
-> after accepting the connection. This is most useful when the
-> transport is not raw TCP, like with SSL for example.
-
-### accept_ack(CSocket, Timeout) -> ok
-
-> Types:
->  *  CSocket = any()
->  *  Timeout = timeout()
->
-> Perform post-accept initialization of the connection.
->
-> This function will be called by connection processes
-> before performing any socket operation. It allows
-> transports that require extra initialization to perform
-> their task and make the socket ready to use.
-
-### close(CSocket) -> ok
-
-> Types:
->  *  CSocket = any()
->
-> Close the given socket.
-
-### controlling_process(CSocket, Pid)
-	-> ok | {error, closed | not_owner | atom()}
-
-> Types:
->  *  CSocket = any()
->  *  Pid = pid()
->
-> Change the controlling process for the given socket.
->
-> The controlling process is the process that is allowed to
-> perform operations on the socket, and that will receive
-> messages from the socket when active mode is used. When
-> the controlling process dies, the socket is closed.
-
-### listen(TransOpts) -> {ok, LSocket} | {error, atom()}
-
-> Types:
->  *  TransOpts = any()
->  *  LSocket = any()
->
-> Listen for connections on the given port.
->
-> The port is given as part of the transport options under
-> the key `port`. Any other option is transport dependent.
->
-> The socket returned by this call can then be used to
-> accept connections. It is not possible to send or receive
-> data from the listening socket.
-
-### messages() -> {OK, Closed, Error}
-
-> Types:
->  *  OK = Closed = Error = atom()
->
-> Return the atoms used to identify messages sent in active mode.
-
-### name() -> Name
-
-> Types:
->  *  Name = atom()
->
-> Return the name of the transport.
-
-### peername(CSocket) -> {ok, {IP, Port}} | {error, atom()}
-
-> Types:
->  *  CSocket = any()
->  *  IP = inet:ip_address()
->  *  Port = inet:port_number()
->
-> Return the IP and port of the remote endpoint.
-
-### recv(CSocket, Length, Timeout)
-	-> {ok, Packet} | {error, closed | timeout | atom()}
-
-> Types:
->  *  CSocket = any()
->  *  Length = non_neg_integer()
->  *  Timeout = timeout()
->  *  Packet = iodata() | any()
->
-> Receive data from the given socket when in passive mode.
->
-> Trying to receive data from a socket that is in active mode
-> will return an error.
->
-> A length of 0 will return any data available on the socket.
->
-> While it is possible to use the timeout value `infinity`,
-> this is highly discouraged as this could cause your process
-> to get stuck waiting for data that will never come. This may
-> happen when a socket becomes half-open due to a crash of the
-> remote endpoint. Wi-Fi going down is another common culprit
-> of this issue.
-
-### send(CSocket, Packet) -> ok | {error, atom()}
-
-> Types:
->  *  CSocket = any()
->  *  Packet = iodata()
->
-> Send data to the given socket.
-
-### sendfile(CSocket, File)
-	-> sendfile(CSocket, File, 0, 0, [])
-### sendfile(CSocket, File, Offset, Bytes)
-	-> sendfile(CSocket, File, Offset, Bytes, [])
-### sendfile(CSocket, File, Offset, Bytes, SfOpts)
-	-> {ok, SentBytes} | {error, atom()}
-
-> Types:
->  *  CSocket = any()
->  *  File = file:filename_all() | file:fd()
->  *  Offset = non_neg_integer()
->  *  Bytes = SentBytes = non_neg_integer()
->  *  SfOpts = sendfile_opts()
->
-> Send data from a file to the given socket.
->
-> The file may be sent full or in parts, and may be specified
-> by its filename or by an already open file descriptor.
->
-> Transports that manipulate TCP directly may use the
-> `file:sendfile/{2,4,5}` function, which calls the sendfile
-> syscall where applicable (on Linux, for example). Other
-> transports can use the `sendfile/6` function exported from
-> this module.
-
-### setopts(CSocket, TransOpts) -> ok | {error, atom()}
-
-> Types:
->  *  CSocket = any()
->  *  TransOpts = any()
->
-> Change transport options for the given socket.
->
-> This is mainly useful for switching to active or passive mode.
-
-### shutdown(CSocket, How) -> ok | {error, atom()}
-
-> Types:
->  *  CSocket = any()
->  *  How = read | write | read_write
->
-> Immediately close the socket in one or two directions.
-
-### sockname(CSocket) -> {ok, {IP, Port}} | {error, atom()}
-
-> Types:
->  *  CSocket = any()
->  *  IP = inet:ip_address()
->  *  Port = inet:port_number()
->
-> Return the IP and port of the local endpoint.
-
-Exports
--------
-
-### sendfile(Transport, CSocket, File, Offset, Bytes, SfOpts)
-	-> {ok, SentBytes} | {error, atom()}
-
-> Types:
->  *  Transport = module()
->  *  CSocket = any()
->  *  File = file:filename_all() | file:fd()
->  *  Offset = non_neg_integer()
->  *  Bytes = SentBytes = non_neg_integer()
->  *  SfOpts = sendfile_opts()
->
-> Send data from a file to the given socket.
->
-> This function emulates the function `file:sendfile/{2,4,5}`
-> and may be used when transports are not manipulating TCP
-> directly.
