I am trying to write a program which would trace the statistics of the bandwidth  usage , the no. of packets lost , the no. of packets sent and recieved over the network from one IP to another IP , when I am conducting Videoconferencing using NetMeeting .

Are there any C builtin functions for this?

There are no standard functions, but take a look at libpcap:

And winpcap:

Also remember, any packet capturing on host might severely affect performance for high bandwidth applications based on CPU-Power to Bandwidth needed ratio.

The idea scenario will be to use a tap in the middle of the hosts to snoop on packets at physical level.

Other option is to use a switch in between and using the switch statistics to calculate the bandwidth. All mediam to high end switches will have some kind of SNMP/RMON interface to get info like packets transferred.
