Detailed Description

Low-level OS socket handle.

It also allow querying inheritability and changing it (and blocking mode) Example (extracted from unit test):

    bool isInheritable;
 
    // We are testing only the inheritable because on windows there is no reliable
    // way of checking if a non-connected socket is in non-blocking mode
    SocketDescriptor socket;
    SC_TEST_EXPECT(socket.create(SocketFlags::AddressFamilyIPV4, SocketFlags::SocketStream, SocketFlags::ProtocolTcp,
                                 SocketFlags::NonBlocking, SocketFlags::NonInheritable));
    SC_TEST_EXPECT(socket.isValid());
    isInheritable = false;
    SC_TEST_EXPECT(socket.isInheritable(isInheritable));
    SC_TEST_EXPECT(not isInheritable);
    SC_TEST_EXPECT(socket.close());
 
    SC_TEST_EXPECT(socket.create(SocketFlags::AddressFamilyIPV4, SocketFlags::SocketStream, SocketFlags::ProtocolTcp,
                                 SocketFlags::Blocking, SocketFlags::NonInheritable));
    SC_TEST_EXPECT(socket.isValid());
    isInheritable = false;
    SC_TEST_EXPECT(socket.isInheritable(isInheritable));
    SC_TEST_EXPECT(not isInheritable);
    SC_TEST_EXPECT(socket.close());
 
    SC_TEST_EXPECT(socket.create(SocketFlags::AddressFamilyIPV4, SocketFlags::SocketStream, SocketFlags::ProtocolTcp,
                                 SocketFlags::Blocking, SocketFlags::Inheritable));
    SC_TEST_EXPECT(socket.isValid());
    isInheritable = false;
    SC_TEST_EXPECT(socket.isInheritable(isInheritable));
    SC_TEST_EXPECT(isInheritable);
    SC_TEST_EXPECT(socket.close());

Member Function Documentation

create()

Result SC::SocketDescriptor::create	(	SocketFlags::AddressFamily	addressFamily,
		SocketFlags::SocketType	socketType = SocketFlags::SocketStream,
		SocketFlags::ProtocolType	protocol = SocketFlags::ProtocolTcp,
		SocketFlags::BlockingType	blocking = SocketFlags::Blocking,
		SocketFlags::InheritableType	inheritable = SocketFlags::NonInheritable
	)

Creates a new Socket Descriptor of given family, type, protocol.

Parameters

addressFamily	Address family (IPV4 / IPV6)
socketType	Socket type (Stream or Dgram)
protocol	Protocol (TCP or UDP)
blocking	If the socket should be created in blocking mode
inheritable	If the socket should be inheritable by child processes

Returns

Valid Result if a socket with the requested options has been successfully created

getAddressFamily()

Result SC::SocketDescriptor::getAddressFamily

(

SocketFlags::AddressFamily &

addressFamily

)

const

Get address family (IPV4 / IPV6) of this socket.

Parameters

[out]

addressFamily

The address family of this socket (if Result is valid)

Returns

Valid Result the address family for this socket has been queried successfully

isInheritable()

Result SC::SocketDescriptor::isInheritable

(

bool &

value

)

const

Check if socket is inheritable by child processes.

Parameters

[out]

value

if set to true indicates that this socket is inheritable by child processes

Returns

Valid Result if the inheritable status for this socket has been queried successfully

setBlocking()

Result SC::SocketDescriptor::setBlocking

(

bool

value

)

Changes the blocking flag for this socket (if IO reads / writes should be blocking or not)

Parameters

value

true if this socket should be made blocking, false for non-blocking

Returns

Valid Result if it has been possible changing the blocking status of this socket

setInheritable()

Result SC::SocketDescriptor::setInheritable

(

bool

value

)

Changes the inheritable flag for this socket.

Parameters

value

true if this socket should be made inheritable, false for non-inheritable

Returns

Valid Result if it has been possible changing the inheritable status of this socket
