No it is not. Some of your assumtions are likely wrong.
Here's some things to check:
* Can your server and workstation can interpret this structure the same
way. If both runs on a similar CPU, running a similar OS, and your
program is compiled by the same compiler , then probably yes.
If not you need to figure out how the struct is represented
internally on both machines and convert between them in some way.
* Are you sure you read the entire struct on the receiving end, and not
just parts of it ? One read/recv call might just give you parts of the
data that was just sent. Be sure even the write call writes
very thing, write can write less than you tell it to.
* Plain old bug. You might just have a bug somewhere. Show the entire
source code if you want anyone to verify.
Remember to check rethrn codes of /all/ calls, etc.
