WebThe inet_addr () function converts the Internet host address cp from IPv4 numbers-and-dots notation into binary data in network byte order. If the input is invalid, INADDR_NONE (usually -1) is returned. Use of this function is problematic because -1 is a valid address (255.255.255.255). WebOct 12, 2024 · Any datagrams queued for receipt are discarded if name is different from the previous connect. For connectionless sockets, name can indicate any valid address, including a broadcast address. However, to connect to a broadcast address, a socket must use setsockopt to enable the SO_BROADCAST option.

Webby the file descriptor sockfd. addrlenspecifies the size, in bytes, of the address structure pointed to by addr. Traditionally, this operation is called “assigning a name to a socket”. It is normally necessary to assign a local address using bind() before a SOCK_STREAM socket may receive connections (see Webnumber. In this example, the IP address is specified as INADDR_ANY to receive datagrams that are addressed to the multicast group. The setsockopt()API uses the IP_ADD_MEMBERSHIP socket option, which joins the multicast group that receives the datagrams. When joining a group, specify the class D group address along with the IP WebEach membership is associated with a single interface. You can join the same group on more than one interface. Specify the imr_interface address as INADDR_ANY to choose the default multicast interface. You can also specify one of the host's local addresses to choose a particular multicast-capable interface. great fun questions to ask people
