Hi,

I'm currently trying implementing a modified TCP state machine and I'm 
going through the code looking for all the systems calls ( eg. the active 
open calls and close connection calls) to TCP and all of it's outputs.

Would anyone know of a document that already has this information?  I 
will also be tackling the IP stack as well, so any info on what systems 
calls it receives and what it outputs would also be of great help.

Thank you,
Tony
