    Hi Michael,

    This snapshot supports the NNTP extension MAXARTNUM

    Oh, you were quick to add support for it. Thanks!

    (Yes, I know MAXARTNUM is far easier to implement in news readers than
    in news servers!)

    flnews is written in C90/C++98, therefore there may be no 64-bit data
    type available. The data type "unsigned long int" is internally used for article numbers and ULONG_MAX as limit.

    This means that on machines where "unsigned long int" is 32-bit wide,
    there are still much more article numbers (beyond 2^31-1) usable with
    the MAXARTNUM extension.

    MAXARTNUM is no longer advertised after capability refresh.

    Hi Michael,

    This means that on machines where "unsigned long int" is 32-bit wide,
    there are still much more article numbers (beyond 2^31-1) usable with
    the MAXARTNUM extension.

    Yes, an extra double number of articles :)

    | [=>] CAPABILITIES
    | [<=] 101 capability list follows:
    | MAXARTNUM 18446744073709551616

    Oh, strange that 2^64 has been advertised. I've contacted the news
    admin. Now fixed!

    MAXARTNUM 18446744073709551615


    | [=>] MAXARTNUM 18446744073709551615
    | [<=] 202 18446744073709551615 is our mutual maximum article number.

    You can then have access to large article numbers:

    GROUP local.test.maxartnum
    211 18 2147483646 2147483663 local.test.maxartnum group selected.
