Bypassing the wireshark/tshark interface to use the dissector

Dear all, thanks for your attention.

I need to design a class that dissects and filter a protocol without having to install the whole wireshark program. This is because i do not require the other dissectors which are unused and i would like my program to run at a high speed to accommodate traffic that i am receiving.

Is there a way to directly access and use the dissectors?

If yes, how? could you please provide me examples on how to use it in the class?

I have been following this conversation : http://www.wireshark.org/lists/wireshark-users/201006/msg00020.html and sadly the conclusion is to use tshark.

Thanks for your time

Regards, eddie choo
