#51 VOS: change underlying function for vos_dottedIP

[mike]

vos_dottedIP uses inet_addr() to convert form dooted decimal string to uint32_t. This involves the risk to get -1 returned in case of invalid addresses given in the string. Please check inet_aton() as replacement - see manpage excerpt below:

   inet_aton() converts the Internet host address  cp  from  the  standard
   numbers-and-dots  notation into binary data and stores it in the struc-
   ture that inp points to. inet_aton() returns non-zero if the address is
   valid, zero if not.

   The  inet_addr()  function  converts  the Internet host address cp from
   numbers-and-dots notation into binary data in network byte  order.   If
   the input is invalid, INADDR_NONE (usually -1) is returned.  This is an
   obsolete interface to inet_aton(), described immediately above;  it  is
   obsolete   because   -1  is  a  valid  address  (255.255.255.255),  and
   inet_aton() provides a cleaner way to indicate error return.

Resolved for Posix-path, only. Windows does not seem to have inet_aton()? What about vxWorks?

[mike]

A prototype for getting around the 255.255.255.255 problem induced by negative return value "-1" is given for MS Windows, POSIX and vxWorks in [r1332].

Got also some comments in for all parties interested in the differences between the worlds.

Did not invest time on the whereabouts/history of the const qualifier (missing in vxWorks).

Closing this ticket after revisting the code changes a 2nd time.
