Re: TCP/IP stack

i am a student of comp sc in india. this is my final
yr project. so i would hv to do it myself :| . thanx
for the help.

When creating the TCP/IP stack i have used
_REG_PRODIRER_DOWN. Now the question is when
advertising I have to send a packet upwards using,
alloc_up_npkt . but the STACK is a down producer for
io-net. So is advertising necessary in this case, at
all? if yes, then is the method same as that of a
network card ( as given in the documentation ).

Also... is npm-ttcpip.so open source or freely
downloadable? can i view the source? is there any
elaborate documentation or any help if i want to write
a driver as a TCP/IP stack for QNX, not a hardware
driver. 

Please Help...
