Detailed Documentation

This class implements a raw socket.

Construction

RawSocketImpl()

Creates an unconnected IPv4 raw socket with IPPROTO_RAW.

RawSocketImpl(
    IPAddress::Family family,
    int proto = IPPROTO_RAW
    )

Creates an unconnected raw socket.

The socket will be created for the given address family.

RawSocketImpl(poco_socket_t sockfd)

Creates a RawSocketImpl using the given native socket.

Methods

virtual
void
init(int af)

Creates the underlying native socket.

Subclasses must implement this method so that it calls initSocket() with the appropriate arguments.

The default implementation creates a stream socket.
