\macro Q_CLASSINFO(Name, Value) | |
Definition at line 50 of file qabstractsocketengine_p.h.
Specifies which fields in the IP packet header are desired in the call to readDatagram().
\value WantNone caller isn't interested in the packet metadata \value WantDatagramSender caller wants the sender address and port number \value WantDatagramDestination caller wants the packet's destination address and port number (this option is useful to distinguish multicast packets from unicast) \value WantDatagramHopLimit caller wants the packet's remaining hop limit or time to live (this option is useful in IPv4 multicasting, where the TTL is used to indicate the realm) \value WantAll this is a catch-all value to indicate the caller is interested in all the available information
