Currently I made one breaking change that IMO cannot be prevented without
tons of workaround code.
That is type change of TCustomWSocket public field/property "sin" from
TSockAddrIn to TSockAddrIn6. TSockAddrIn6 can be passed to all old
functions by typ casting it to TSockAddrIn and passing the size of
TSockAddrIn.
However if anybody has an idea how to easily avoid this breaking change
please
let me know.
Keep the current property as it is and use it for anything related to IPv4.
Create a new property sin6 : TSockAddrIn6 and use if for IPv6.
Anyone recompiling an existing program with IPv4 will have no change to do
in his code.
Anyone willing to support IPv6 will have to do some changes, including this
one.
Instead of creating two variables, maybe only create one, the one being the
largest. Then map the properties sin and sin6 to the same location using
getter and setter. Propably the variable could be a variant record with both
types to makes the code clearer because this would remove most typecasts.
