NetLibSocketOptionGet Call on POSE 2.1d26

[Andreas Paepcke]

We've been successfully making the following NetLibSocketOptionGet call on
previous versions of the Emulator, on Palm III, and on Palm IIIx. Always
worked. Only with Emulator version 2.1d26, this generates an error 4612
(bad parm?):

        r = NetLibSocketOptionGet(
                AppNetRefnum,
                socket,
                netSocketOptLevelTCP,
                netSocketOptTCPMaxSeg,
                &TCPMaxSeg,
                &size,
                0,
                &err);

Anything known about this as an issue?

Thanks,

Andreas
