typedef struct SilcSocketConnectionStruct *SilcSocketConnection;

    This context is forward declaration for the SilcSocketConnectionStruct.
    This is allocated by the silc_socket_alloc and freed by the
    silc_socket_free function. The silc_socket_dup can be used to
    increase the reference counter of the context. The data is freed
    by the silc_socket_free function only after the reference counter
    hits zero.
