/**  test coder preface:
    1. the BSD socket function will meet "unresolved external symbol error" on Windows platform
    if you are not including ws2_32.lib in makefile.mk,  the including format will be like this:

    .IF "$(GUI)" == "WNT"
    SHL1STDLIBS +=  $(SOLARLIBDIR)$/cppunit.lib
    SHL1STDLIBS +=  ws2_32.lib
    .ENDIF

    likewise on Solaris platform.
    .IF "$(GUI)" == "UNX"
    SHL1STDLIBS+=$(SOLARLIBDIR)$/libcppunit$(DLLPOSTFIX).a
    SHL1STDLIBS += -lsocket -ldl -lnsl
    .ENDIF

    2. since the Socket implementation of osl is only IPv4 oriented, our test are mainly focus on IPv4
    category.

    3. some fragment of Socket source implementation are lack of comment so it is hard for testers
    guess what the exact functionality or usage of a member.  Hope the Socket section's comment
    will be added.

    4. following functions are declared but not implemented:
    inline sal_Bool SAL_CALL operator== (const SocketAddr & Addr) const;
