Network.BSD

Either a host name e.g., "haskell.org" or a numeric host address string consisting of a dotted decimal IPv4 address or an IPv6 address e.g., "192.168.0.1".

The raw network byte order number is read using host byte order. Therefore on little-endian architectures the byte order is swapped. For example 127.0.0.1 is represented as 0x0100007f on little-endian hosts and as 0x7f000001 on big-endian hosts.

For direct manipulation prefer hostAddressToTuple and tupleToHostAddress.

Address families. The AF_xxxxx constants are widely used as synonyms for the corresponding PF_xxxxx protocol family values, to which they are numerically equal in mainstream socket API implementations.

Strictly correct usage would be to pass the PF_xxxxx constants as the first argument when creating a Socket, while the AF_xxxxx constants should be used as addrFamily values with getAddrInfo. For now only the AF_xxxxx constants are provided.

Some of the defined patterns may be unsupported on some systems: see isSupportedFamily.

Calling getHostName returns the standard host name for the current processor, as set at boot time.

gethostname(2).

Representation of the POSIX hostent structure defined in netdb.h.

Resolve a HostName to IPv4 address.

Get a HostEntry corresponding to the given address and family. Note that only IPv4 is currently supported.

Convenience function extracting one address in a HostEntry. Returns error if HostEntry contains no addresses.

Retrieve list of all HostEntry via gethostent(3).

Representation of the POSIX servent structure defined in netdb.h.

Either a service name e.g., "http" or a numeric port number.

Port number. Use the Num instance (i.e. use a literal) to create a PortNumber value.

>>> 1 :: PortNumber1>>> read "1" :: PortNumber1>>> show (12345 :: PortNumber)"12345">>> 50000 < (51000 :: PortNumber)True>>> 50000 < (52000 :: PortNumber)True>>> 50000 + (10000 :: PortNumber)60000
