## Detailed Description

## Enumeration Type Documentation

enum Gio::Socket::MsgFlags
| strong

Flags used in g_socket_receive_message() and g_socket_send_message().

The flags listed in the enum are some commonly available flags, but the values used for them are the same as on the platform, and any other flags are passed in/out as is. So to use a platform specific flag, just include the right system header and pass in the flag.

Since glibmm 2.22:

Bitwise operators:
  `Socket::MsgFlags operator|(Socket::MsgFlags, Socket::MsgFlags)`
  `Socket::MsgFlags operator&(Socket::MsgFlags, Socket::MsgFlags)`
  `Socket::MsgFlags operator^(Socket::MsgFlags, Socket::MsgFlags)`
  `Socket::MsgFlags operator~(Socket::MsgFlags)`
  `Socket::MsgFlags& operator|=(Socket::MsgFlags&, Socket::MsgFlags)`
  `Socket::MsgFlags& operator&=(Socket::MsgFlags&, Socket::MsgFlags)`
  `Socket::MsgFlags& operator^=(Socket::MsgFlags&, Socket::MsgFlags)`

Enumerator
NONE | No flags.
OOB | Request to send/receive out of band data.
PEEK | Read data from the socket without removing it from the queue.
DONTROUTE | Don't use a gateway to send out the packet, only send to hosts on directly connected networks.

enum Gio::Socket::Protocol
| strong

A protocol identifier is specified when creating a Socket, which is a family/type specific identifier, where 0 means the default protocol for the particular family/type.

This enum contains a set of commonly available and used protocols. You can also pass any other identifiers handled by the platform in order to use protocols not listed here.

Since glibmm 2.22:

Enumerator
UNKNOWN | The protocol type is unknown.
DEFAULT | The default protocol for the family/type.
TCP | TCP over IP.
UDP | UDP over IP.
SCTP | SCTP over IP.

enum Gio::Resolver::RecordType
| strong

The type of record that g_resolver_lookup_records() or g_resolver_lookup_records_async() should retrieve.

The records are returned as lists of Variant tuples. Each record type has different values in the variant tuples returned.

Gio::Resolver::RecordType::SRV records are returned as variants with the signature '(qqqs)', containing a guint16 with the priority, a guint16 with the weight, a guint16 with the port, and a string of the hostname.

Gio::Resolver::RecordType::MX records are returned as variants with the signature '(qs)', representing a guint16 with the preference, and a string containing the mail exchanger hostname.

Gio::Resolver::RecordType::TXT records are returned as variants with the signature '(as)', representing an array of the strings in the text record.

Gio::Resolver::RecordType::SOA records are returned as variants with the signature '(ssuuuuu)', representing a string containing the primary name server, a string containing the administrator, the serial as a guint32, the refresh interval as guint32, the retry interval as a guint32, the expire timeout as a guint32, and the ttl as a guint32.

Gio::Resolver::RecordType::NS records are returned as variants with the signature '(s)', representing a string of the hostname of the name server.

Since glibmm 2.34:

Enumerator
SRV | Lookup DNS SRV records for a domain.
MX | Lookup DNS MX records for a domain.
TXT | Lookup DNS TXT records for a name.
SOA | Lookup DNS SOA records for a zone.
NS | Lookup DNS NS records for a domain.

enum Gio::UnixSocketAddress::Type
| strong

The type of name used by a UnixSocketAddress.

Gio::UnixSocketAddress::Type::PATH indicates a traditional unix domain socket bound to a filesystem path. Gio::UnixSocketAddress::Type::ANONYMOUS indicates a socket not bound to any name (eg, a client-side socket, or a socket created with socketpair()).

For abstract sockets, there are two incompatible ways of naming them; the man pages suggest using the entire `struct sockaddr_un` as the name, padding the unused parts of the sun_path field with zeroes; this corresponds to Gio::UnixSocketAddress::Type::ABSTRACT_PADDED. However, many programs instead just use a portion of sun_path, and pass an appropriate smaller length to bind() or connect(). This is Gio::UnixSocketAddress::Type::ABSTRACT.

Since glibmm 2.26:

Enumerator
INVALID | Invalid.
ANONYMOUS | Anonymous.
PATH | A filesystem path.
ABSTRACT | An abstract name.
ABSTRACT_PADDED | An abstract name, 0-padded to the full length of a unix socket name.

enum Gio::Socket::Type
| strong

Flags used when creating a Socket.

Some protocols may not implement all the socket types.

Since glibmm 2.22:

Enumerator
INVALID | Type unknown or wrong.
STREAM | Reliable connection-based byte streams (e.g. TCP).
DATAGRAM | Connectionless, unreliable datagram passing. (e.g. UDP).
SEQPACKET | Reliable connection-based passing of datagrams of fixed maximum length (e.g. SCTP).

## Function Documentation

SignalSocket Gio::signal_socket | ( | const Glib::RefPtr< Glib::MainContext >& | context = `Glib::RefPtr< Glib::MainContext >()` | ) |

Convenience socket signal.

Parameters

  context | The main context to which the signal shall be attached.

Returns
  A signal proxy; you want to use SignalSocket::connect().
