What is Socketpair used for?
The socketpair function creates a pair of unnamed UNIX domain sockets of the specified type and the optionally specified protocol. The function returns two descriptors that represent the sockets in the socket pair.
How socketpair works?
socketpair creates two sockets which are already connected to each other. A common use case is the communication between a parent and a child process: the parent creates the socket pair, forks the child and then child and parent can communicate through their end of the socket pair with each other.
What is Sock_seqpacket?
SOCK_SEQPACKET, for a connection-oriented socket that preserves message boundaries and delivers messages in the order that they were sent.” The standard permits that you get reordered packets with SOCK_DGRAM. (In other words, if an OS hands them to you in order, that is an implementation-specific feature.
What is Setsockopt?
The setsockopt function sets the current value for a socket option associated with a socket of any type, in any state. Although options can exist at multiple protocol levels, they are always present at the uppermost socket level.
What is a Sock_stream?
SOCK_STREAM. Provides sequenced, two-way byte streams with a transmission mechanism for stream data. This socket type transmits data on a reliable basis, in order, and with out-of-band capabilities. In the UNIX domain, the SOCK_STREAM socket type works like a pipe.
What is Datagramsocket explain in detail with example?
Datagram socket is a type of network socket which provides connection-less point for sending and receiving packets. Every packet sent from a datagram socket is individually routed and delivered. It can also be used for sending and receiving broadcast messages.
What is So_keepalive?
The SO_KEEPALIVE socket option is designed to allow an application to enable keep-alive packets for a socket connection. To query the status of this socket option, call the getsockopt function.
What is So_sndbuf?
SO_SNDBUF int Specifies the total per-socket buffer space reserved for sends. With more detail later on: SO_RCVBUF and SO_SNDBUF. When a Windows Sockets implementation supports the SO_RCVBUF and SO_SNDBUF options, an application can request different buffer sizes (larger or smaller).
What are the 3 types of sockets?
What are the different types of socket?
- Hex Sockets. Hex sockets are the most common type of socket and come in two main types: hex/6 point sockets and bi-hex/12 point sockets.
- Socket Bits.
- Impact Socket.
- Spark Plug Socket.
- Insulated Sockets.
- Pass Through Sockets.
- Adjustable Multi Sockets.
- Oil Filter Socket.
What is the difference between Sock_stream and Sock_dgram?
SOCK_DGRAM is a datagram-oriented socket, regardless of the transport protocol used. UDP is one, but not the only, transport that uses datagrams. SOCK_STREAM is a stream-oriented socket, regardless of the transport protocol used. TCP is one, but not the only, transport that uses streams.
What is DatagramSocket and DatagramPacket?
DatagramPacket object is the data container. DatagramSocket is the mechanism used to send or receive the DatagramPackets.
What is DatagramSocket in computer network?
There are two types of Sockets: the datagram socket and the stream socket. Datagram Socket : This is a type of network which has connection less point for sending and receiving packets.
What is Tcp_keepintvl?
tcp_keepintvl. Specifies the interval between packets that are sent to validate the connection. This value is defined in half second ( 1/2 ) unit, and defaults to 150 (75 seconds). The tcp_keepintvl parameter is a runtime parameter. Windows.
What does Inaddr_any mean?
This is an IP address that is used when we don’t want to bind a socket to any specific IP. Basically, while implementing communication, we need to bind our socket to an IP address. When we don’t know the IP address of our machine, we can use the special IP address INADDR_ANY .
What are the 5 different types of socket?
There are several types of socket wrenches, however, each of which uses a different method of operation.
- #1) Ratcheting. Ratching is the most common type of socket wrench.
- #2) Flex Head. There are flex-head socket wrenches that have a swiveling head.
- #3) T-Handle.
- #4) Nut Driver.
- #5) Gearless.
What are the 4 different types of sockets?
What is Sock_dgram used for?
The datagram socket (SOCK_DGRAM) interface defines a connectionless service for datagrams, or messages. Datagrams are sent as independent packets. The reliability is not guaranteed, data can be lost or duplicated, and datagrams can arrive out of order.
What is Sock_stream in socket?
What is DatagramSocket explain it with example?
What is DatagramPacket?
Datagram packets are used to implement a connectionless packet delivery service. Each message is routed from one machine to another based solely on information contained within that packet. Multiple packets sent from one machine to another might be routed differently, and might arrive in any order.
What is SO_KEEPALIVE?
What is Tcp_fin_timeout?
tcp_fin_timeout (integer; default: 60) This specifies how many seconds to wait for a final FIN packet. before the socket is forcibly closed. This is strictly a viola- tion of the TCP specification, but required to prevent denial-
What is the 0.0 0.0 IP address?
A 0.0. 0.0 address indicates the client isn’t connected to a TCP/IP network, and a device may give itself a 0.0. 0.0 address when it is offline.
What is Ipproto_ip?
IPPROTO_IP creates a socket that sends/receives raw data for IPv4-based protocols (TCP, UDP, etc). It will handle the IP headers for you, but you are responsible for processing/creating additional protocol data inside the IP payload.
What are 12 point sockets used for?
The additional points make these sockets easier to connect with the heads of fasteners. This is ideal if you are trying to work on a fastener that is hard to see or you cannot see at all. 12 point sockets are also great for use in tight spaces as they allow you to connect to a fastener at more angles.
