- native sockets library
- address-info? Vprocedure
Checks whether V is an address information record.
- make-address-info FAMILY TYPE HOST PORTprocedure
Constructs a new address information record from the given FAMILY ('ipv4 or 'ipv6), a socket TYPE ('tcp, 'udp or 'raw), a numeric HOST address encoded as a string and a PORT that is a either a positive integer or #f.
- address-info-family INFOprocedure
Extracts the address family from an address information record.
- address-info-type INFOprocedure
Extracts the socket type from an address information record.
- address-info-host INFOprocedure
Extracts the numeric host address from an address information record.
- address-info-port INFOprocedure
Extracts the port from an address information record.
- (address-infos HOST [#:port PORT] [#:family FAMILY] [#:type TYPE] [#:server? SERVER] [#:numeric? NUMERIC])procedure
Tries to lookup socket addresses for the given HOST and/or PORT. If the lookup is successful, the procedure returns a list of address information records. Otherwise it returns #f.
For a successful lookup you must at least specify a HOST or a PORT. If no HOST is specified, the function defaults to server mode lookup and will return wildcard addresses. This behaviour can be changed using the SERVER flag.
By default, the procedure will return address information records for all suitable supported protocol families and socket types. The FAMILY argument may be used to filter for 'ipv4 or 'ipv6 addresses. The TYPE argument may be used to filter for 'tcp / 'stream, 'udp / 'datagram or 'raw socket types.
Unless the NUMERIC flag is set to a true value, the procedure will convert hostnames into numeric network addresses.
