Socket

Initializes a new instance of the Socket class using the specified socket type and protocol. If the operating system supports IPv6, this constructor creates a dual-mode socket; otherwise, it creates an IPv4 socket.

socket

The socket() function shall create an unbound socket in a communications domain, and return a file descriptor that can beused in later function calls that operate on sockets. The file descriptor shall be allocated as described in File Descriptor Allocation.

The type argument specifies the socket type, which determines the semantics of communication over the socket. Thefollowing socket types are defined; implementations may specify additional socket types:

File Descriptor Allocation, accept, bind, connect, getsockname, getsockopt, listen, recv, recvfrom, recvmsg, send, sendmsg, setsockopt, shutdown, socketpair

Dry socket (alveolar osteitis) is a painful dental condition that sometimes happens after you have a permanent adult tooth extracted. Dry socket is when the blood clot at the site of the tooth extraction fails to develop, or it dislodges or dissolves before the wound has healed.

Normally, a blood clot forms at the site of a tooth extraction. This blood clot serves as a protective layer over the underlying bone and nerve endings in the empty tooth socket. The clot also provides the foundation for the growth of new bone and for the development of soft tissue over the clot.

Exposure of the underlying bone and nerves results in intense pain, not only in the socket but also along the nerves radiating to the side of your face. The socket becomes inflamed and may fill with food debris, adding to the pain. If you develop dry socket, the pain usually begins one to three days after your tooth is removed.

Dry socket is the most common complication following tooth extractions, such as the removal of third molars (wisdom teeth). Over-the-counter medications alone won't be enough to treat dry socket pain. Your dentist or oral surgeon can offer treatments to relieve your pain.

Painful, dry socket rarely results in infection or serious complications. However, potential complications may include delayed healing of or infection in the socket or progression to chronic bone infection (osteomyelitis).

Your dentist or oral surgeon will take a number of steps to ensure proper healing of the socket and to prevent dry socket. These steps may include recommending one or more of these medications, which may help prevent dry socket:

You'll receive instructions about what to expect during the healing process after a tooth extraction and how to care for the wound. Proper at-home care after a tooth extraction helps promote healing and prevent damage to the wound. These instructions will likely address the following issues, which can help prevent dry socket:

On Unix, the local domain is also known as the Unix domain. The path is afile system pathname. It gets truncated to an OS-dependent length ofsizeof(sockaddr_un.sun_path) - 1. Typical values are 107 bytes on Linux and103 bytes on macOS. If a Node.js API abstraction creates the Unix domain socket,it will unlink the Unix domain socket as well. For example,net.createServer() may create a Unix domain socket andserver.close() will unlink it. But if a user creates the Unix domainsocket outside of these abstractions, the user will need to remove it. The sameapplies when a Node.js API creates a Unix domain socket but the program thencrashes. In short, a Unix domain socket will be visible in the file system andwill persist until unlinked.

On Windows, the local domain is implemented using a named pipe. The path mustrefer to an entry in \\?\pipe\ or \\.\pipe\. Any characters are permitted,but the latter may do some processing of pipe names, such as resolving ..sequences. Despite how it might look, the pipe namespace is flat. Pipes willnot persist. They are removed when the last reference to them is closed.Unlike Unix domain sockets, Windows will close and remove the pipe when theowning process exits.

Returns the bound address, the address family name, and port of the serveras reported by the operating system if listening on an IP socket(useful to find which port was assigned when getting an OS-assigned address): port: 12346, family: 'IPv4', address: '127.0.0.1' .

By default (allowHalfOpen is false) the socket will send an end oftransmission packet back and destroy its file descriptor once it has written outits pending write queue. However, if allowHalfOpen is set to true, thesocket will not automatically end() its writable side,allowing the user to write arbitrary amounts of data. The user must callend() explicitly to close the connection (i.e. sending aFIN packet back).

net.Socket has the property that socket.write() always works. This is tohelp users get up and running quickly. The computer cannot always keep upwith the amount of data that is written to a socket. The network connectionsimply might be too slow. Node.js will internally queue up the data written to asocket and send it out over the wire when it is possible.

The consequence of this internal buffering is that memory may grow.Users who experience large or growing bufferSize should attempt to"throttle" the data flows in their program withsocket.pause() and socket.resume().

If true,socket.connect(options[, connectListener]) wascalled and has not yet finished. It will stay true until the socket becomesconnected, then it is set to false and the 'connect' event is emitted. Notethat thesocket.connect(options[, connectListener])callback is a listener for the 'connect' event.

The string representation of the local IP address the remote client isconnecting on. For example, in a server listening on '0.0.0.0', if a clientconnects on '192.168.1.1', the value of socket.localAddress would be'192.168.1.1'.

Opposite of unref(), calling ref() on a previously unrefed socket willnot let the program exit if it's the only socket left (the default behavior).If the socket is refed calling ref again will have no effect.

Close the TCP connection by sending an RST packet and destroy the stream.If this TCP socket is in connecting status, it will send an RST packet and destroy this TCP socket once it is connected.Otherwise, it will call socket.destroy with an ERR_SOCKET_CLOSED Error.If this is not a TCP socket (for example, a pipe), calling this method will immediately throw an ERR_INVALID_HANDLE_TYPE Error.

When the connection is established, a 'connect' event will be emittedon the returned socket. The last parameter connectListener, if supplied,will be added as a listener for the 'connect' event once.

This function creates a new net.Socket with all options set to default,immediately initiates connection withsocket.connect(path[, connectListener]),then returns the net.Socket that starts the connection.

This function creates a new net.Socket with all options set to default,immediately initiates connection withsocket.connect(port[, host][, connectListener]),then returns the net.Socket that starts the connection.

If allowHalfOpen is set to true, when the other end of the socketsignals the end of transmission, the server will only send back the end oftransmission when socket.end() is explicitly called. For example, in thecontext of TCP, when a FIN packed is received, a FIN packed is sentback only when socket.end() is explicitly called. Until then theconnection is half-closed (non-readable but still writable). See 'end'event and RFC 1122 (section 4.2.2.13) for more information.

If pauseOnConnect is set to true, then the socket associated with eachincoming connection will be paused, and no data will be read from its handle.This allows connections to be passed between processes without any data beingread by the original process. To begin reading data from a paused socket, callsocket.resume().

The K-TOR Power Box 50 pedal power generator provides 14 volt DC power and has been designed to charge directly 12-volt sealed lead acid batteries. Devices that plug into an automotive 12-volt socket and are within the maximum power range such as USB outlets can be used. Insure devices plugged in are connected securely. Do not use devices that are loose as a poor connection can create arcing and a fire hazard. K-TOR offers accessories for these purposes such as the 12-volt male to alligator clips, included with the unit. Available to purchase from K-TOR are a 12-volt male to dual 12-volt female socket, 12-volt male to USB and 12-volt male to inverter. Or, purchase a third party 12-volt to Anderson Connectors converter. To run devices that exceed the generators maximum power charge a battery with a Power Box 50 and run an inverter off of that battery. Custom versions with different voltage and current regulation, such as charging lithium batteries, are possible within the maximum capibility of the generator.

All protocols known to the OS are enumerated when the Erlang VM is started. See the OS man page for protocols(5). The protocol level 'socket' is always implemented as SOL_SOCKET and all the others mentioned in the list above are valid, if supported by the platform, enumerated or not.

Warning! When this option is enabled, error messages may arrive on the socket's error queue, which should be read using the message flag errqueue, and using recvmsg/1,2,3,4,5 to get all error information in the message's ctrl field as a control message #level := ip, type := recverr.

A working strategy should be to first poll the error queue using recvmsg/2,3,4 with Timeout =:= 0 and Flags containing errqueue (ignore the return value error, timeout) before reading the actual data to ensure that the error queue gets cleared. And read the data using one of the nowait select_handle() recv functions: recv/3,4, recvfrom/3,4 or recvmsg/3,4,5. Otherwise you might accidentally cause a busy loop in and out of 'select' for the socket.

This call is used with connection oriented socket types (stream or seqpacket). It returns the first pending incoming connection for a listen socket, or waits for one to arrive, and returns the (newly) connected socket. 041b061a72
