QNetworkInterface Class Reference |
Constant | Value | Description |
---|---|---|
QNetworkInterface::IsUp | 0x1 | the network interface is active |
QNetworkInterface::IsRunning | 0x2 | the network interface has resources allocated |
QNetworkInterface::CanBroadcast | 0x4 | the network interface works in broadcast mode |
QNetworkInterface::IsLoopBack | 0x8 | the network interface is a loopback interface: that is, it's a virtual interface whose destination is the host computer itself |
QNetworkInterface::IsPointToPoint | 0x10 | the network interface is a point-to-point interface: that is, there is one, single other address that can be directly reached by it. |
QNetworkInterface::CanMulticast | 0x20 | the network interface supports multicasting |
Note that one network interface cannot be both broadcast-based and point-to-point.
The InterfaceFlags type is a typedef for QFlags<InterfaceFlag>. It stores an OR combination of InterfaceFlag values.
Constructs an empty network interface object.
Creates a copy of the the QNetworkInterface object contained in other.
Frees the resources associated with the QNetworkInterface object.
Returns the list of IP addresses that this interface possesses along with their associated netmasks and broadcast addresses.
If the netmask or broadcast address information is not necessary, you can call the allAddresses() function to obtain just the IP addresses.
This convenience function returns all IP addresses found on the host machine. It is equivalent to calling addressEntries() on all the objects returned by allInterfaces() to obtain lists of QHostAddress objects then calling QHostAddress::ip() on each of these.
Returns a listing of all the network interfaces found on the host machine.
Returns the flags associated with this network interface.
Returns the low-level hardware address for this interface. On Ethernet interfaces, this will be a MAC address in string representation, separated by colons.
Other interface types may have other types of hardware addresses. Implementations should not depend on this function returning a valid MAC address.
Returns a QNetworkInterface object for the interface whose internal ID is index. Network interfaces have a unique identifier called the "interface index" to distinguish it from other interfaces on the system. Often, this value is assigned progressively and interfaces being removed and then added again get a different value every time.
This index is also found in the IPv6 address' scope ID field.
Returns a QNetworkInterface object for the interface named name. If no such interface exists, this function returns an invalid QNetworkInterface object.
See also name() and isValid().
Returns true if this QNetworkInterface object contains valid information about a network interface.
Returns the name of this network interface. On Unix systems, this is a string containing the type of the interface and optionally a sequence number, such as "eth0", "lo" or "pcn0". On Windows, it's an internal ID that cannot be changed by the user.
Copies the contents of the QNetworkInterface object contained in other into this one.
