I have run into a seemingly insurmountable problem when communicating
between DEC (Ultrix) and Sun machines using TCP/IP. The two machines
reverse bytes, which is handled by the ntohs, ntohl commands. However,
I have an application sending floats. Interestingly, if one does:
printf("The value should be %f",ntohs(x));
then one gets a sort-of reasonable, predictable answer. However, if one
does:
x = ntohs(x);
printf("x is now %f",x);
then one realizes that the Vax SEEMS to do some funny things with the
high order bits, transforming a very small number into an incorrect,
large one....
any experiences or suggestions on surmounting this would be
appreciated! thanks!
