For instance, your internet browser, which is a software program, will not be able to access data network. There are various causes of windows socket error. Windows socket errors are going to take place frequently unless you clean your computer regularly. As we have seen that viruses and malware cause windows socket error, it is wise to run an antivirus scan on your whole system with any installed antivirus software. You will find many options in the search results.
Download the one that you trust. The socket option for which the value is to be retrieved. The optname value must be a socket option defined within the specified level , or behavior is undefined.
If no error occurs, getsockopt returns zero. The getsockopt function retrieves the current value for a socket option associated with a socket of any type, in any state, and stores the result in optval.
Options can exist at multiple protocol levels, but they are always present at the uppermost socket level. Options affect socket operations, such as the packet routing and OOB data transfer. The value associated with the selected option is returned in the buffer optval.
The integer pointed to by optlen should originally contain the size of this buffer; on return, it will be set to the size of the value returned. For most other options, it will be the size of an integer. The application is responsible for allocating any memory space pointed to directly or indirectly by any of the parameters it specified. If the option was never set with setsockopt , then getsockopt returns the default value for the option. The following options are supported for getsockopt.
The Type column identifies the type of data addressed by optval. For more information on socket options, see Socket Options. The following table lists value for the optname that represent BSD socket options that are not supported by the getsockopt function. More detailed information on some of the socket options for the optname parameter supported by the getsockopt function are listed below.
This option can also be used while a ConnectEx function call is in progress. Checking a connection like this is necessary to see if connections that have been established for a while, without sending any data. It is recommended that applications terminate these connections. The application specifies the device and class to query and the attribute and attribute type. It is expected that the application allocates a buffer, of the necessary size, for the returned parameters.
Windows 8. Socket Options. The address family specification. Possible values for the address family are defined in the Winsock2. On the Windows SDK released for Windows Vista and later, the organization of header files has changed and the possible values for the address family are defined in the Ws2def.
Note that the Ws2def. This provider is installed by default on bit versions of Windows. This address family is supported on Windows XP with SP2 or later if the computer has a Bluetooth adapter and driver installed. The following table lists the possible values for the type parameter supported for Windows Sockets In Windows Sockets 2, new socket types were introduced. An application can dynamically discover the attributes of each available transport protocol through the WSAEnumProtocols function.
So an application can determine the possible socket type and protocol options for an address family and use this information when specifying this parameter.
Socket type definitions in the Winsock2. In Windows Sockets 1. The protocol to be used. The possible options for the protocol parameter are specific to the address family and socket type specified. Possible values for the protocol are defined in the Winsock2. If a value of 0 is specified, the caller does not wish to specify a protocol and the service provider will choose the protocol to use. The table below lists common values for the protocol although many other values are possible.
If no error occurs, socket returns a descriptor referencing the new socket. The socket function causes a socket descriptor and any related resources to be allocated and bound to a specific transport-service provider. Winsock will utilize the first available service provider that supports the requested combination of address family, socket type and protocol parameters. The socket that is created will have the overlapped attribute as a default. Sockets without the overlapped attribute can be created by using WSASocket.
When selecting a protocol and its supporting service provider this procedure will only choose a base protocol or a protocol chain, not a protocol layer by itself.
