Hey, I'm pretty new to this networking stuff in C, and i just got a question abt some example code that i found. This is only part of the Client.c file.
The question is: I want the client to connect to the IP Address which i have to
explicitly set as 'localhost'. But I don't know exactly how I set the IPAddress that the client is to connect to, could someone please tell me where I do that and how?
The comment on this code says, "copies IP address" why do you have to do that?Code:socketAddr.sin_addr.s_addr = ipAddress->s_addr; /* Copies IP address */
Code:int fd; struct in_addr* ipAddress; struct hostent* hostp; struct sockaddr_in socketAddr; char buffer; int numBytes; hostp = gethostbyname("localhost"); ipAddress = (struct in_addr*)hostp->h_addr_list; /* Specify the address we're going to connect to */ socketAddr.sin_family = AF_INET; /* Internet socket */ socketAddr.sin_port = htons(13827); /* Port number */ socketAddr.sin_addr.s_addr = ipAddress->s_addr; /* Copies IP address */ /* Create TCP socket */ fd = socket(AF_INET, SOCK_STREAM, 0); /* Try to connect to our server address */ /* Address cast to generic socket address type, but we need to specify ** the size of the address as the third argument */ connect(fd, (struct sockaddr*)&socketAddr, sizeof(socketAddr));
