| Summary | 0000840: Add SO_DOMAIN and SO_PROTOCOL options for getsockopt() | ||||
| Description | Following the discussion "SO_DOMAIN and SO_PROTOCOL options for getsockopt()" on the austin-group-l mailing-list, I am suggesting the addition of two new features for getsockopt() to be used with sockets. POSIX has a SO_TYPE option for getsockopt() to retrieve the socket type of a given (socket) file descriptor. The socket type is typically set when creating it through a call to: int socket(int domain, int type, int protocol); Unfortunately, there are no (standardized) options to fetch the first domain attribute, or the last protocol attribute. Linux has such options: (http://man7.org/linux/man-pages/man7/socket.7.html) SO_DOMAIN (since Linux 2.6.32) Retrieves the socket domain as an integer, returning a value such as AF_INET6. See socket(2) for details. This socket option is read-only. SO_PROTOCOL (since Linux 2.6.32) Retrieves the socket protocol as an integer, returning a value such as IPPROTO_SCTP. See socket(2) for details. This socket option is read-only. And Solaris has also a SO_DOMAIN option and a bit different SO_PROTOTYPE one: (http://docs.oracle.com/cd/E26505_01/html/816-5170/getsockopt-3socket.html#REFMAN3Bgetsockopt-3socket) SO_DOMAIN get the domain used in the socket (get only) SO_PROTOTYPE for socket in domains PF_INET and PF_INET6, get the underlying protocol number used in the socket. For socket in domain PF_ROUTE, get the address family used in the socket. At last, FreeBSD has a SO_PROTOCOL (no SO_DOMAIN currently) (http://www.freebsd.org/cgi/man.cgi?query=setsockopt&sektion=2) SO_PROTOCOL get the protocol number for the socket (get only) | ||||
| Desired Action | (1) add a SO_DOMAIN options for getsockopt() (invalid for setsockopt()) described as: Retrieve the communications domain in which the socket was created (2) add a SO_PROTOCOL options for getsockopt() (invalid for setsockopt()) described as: Retrieve the protocol to be used with the socket | ||||
