int finger(char *address, char *query)

Finger a host and printf result; debug info & errors go to stderr

Documentation

Finger a host and printf result; debug info & errors go to stderr. It works as follows: First, the port number of the finger service is resolved by a getservbyname call. It should be 79/TCP, which is the default value if the resolution fails.Then the host address is resolved. First we try to treat it as a www.xxx.yyy.zzzz numerical address (via inet_addr). If that fails we try a hostname lookup (via gethostbyname).Now we create a socket (socket(AF_INET, SOCK_STREAM, 0)) and connect to the host (connect(sock, (sockaddr *)&sin, sizeof(sin))).Send query with write, terminated with a <CR/LF>.Finally receive the result with read and printf it out.

Returns:

0 if ok, 1 on error.

Parameters:

address - Internet address of host, may be numerical or by name.
query - Query string to send to finger server, without trailing <CR/LF> sequence.
