Member Function Documentation

Read() [1/2]

virtual ssize_t Dwm::Readable::Read ( int  fd )

pure virtual

Read from a file descriptor.

Returns the number of bytes read on success, -1 on failure.

Implemented in Dwm::Patricia< KeyType, ValueType, KeyEqual >, Dwm::Ipv4Routes< _valueT >, Dwm::Ipv4Address, Dwm::Ipv4Prefix, Dwm::Ipv4PacketHeader, Dwm::Ipv4TcpHeader, Dwm::ProcessInfo, Dwm::Rusage, Dwm::TimeInterval, Dwm::Ipv4UdpHeader, Dwm::TimeValue, Dwm::TimeValue64, Dwm::Ipv6Address, Dwm::Ipv4TcpPacket, Dwm::Ipv4UdpPacket, Dwm::Ipv6Prefix, Dwm::MplsLabel, Dwm::MacAddress, and Dwm::MplsLabelStack.

Read() [2/2]

virtual size_t Dwm::Readable::Read ( FILE *  f )

pure virtual

Read from a FILE pointer.

Returns 1 on success, 0 on failure (fread() semantics).

Implemented in Dwm::Patricia< KeyType, ValueType, KeyEqual >, Dwm::Ipv4Routes< _valueT >, Dwm::Ipv4Address, Dwm::Ipv4Prefix, Dwm::Ipv4PacketHeader, Dwm::Ipv4TcpHeader, Dwm::ProcessInfo, Dwm::Rusage, Dwm::Ipv4UdpHeader, Dwm::TimeInterval, Dwm::TimeValue, Dwm::TimeValue64, Dwm::Ipv4TcpPacket, Dwm::Ipv6Address, Dwm::Ipv4UdpPacket, Dwm::Ipv6Prefix, Dwm::MplsLabel, Dwm::MacAddress, and Dwm::MplsLabelStack.
