Hey there,

I'm writing an analyzer as a plugin and I would like to create some new bro data type (record type to be exact) to hand over some protocol data in a compact form as parameters to the event functions.

For now I have declared the new types in types.bif and defined them in init-bare.bro, but I don't think that this is the right way, because I have to manually modify the bro source files.

Is there a way to declare and define the new type inside the plugin source files, so that the types will be featured in bro after the plugin was installed?

Greetings,

Dane

Hello,

Take a look into this example: [https://github.com/vitalyrepin/uap-bro](https://github.com/vitalyrepin/uap-bro) I have defined three record types in that plugin: DeviceRec, UserAgentRec and AgentRec.

P.S. I think bro-dev is a better mailing list to discuss bro dev. issues: [http://mailman.icsi.berkeley.edu/mailman/listinfo/bro-dev](http://mailman.icsi.berkeley.edu/mailman/listinfo/bro-dev)

Hey

thanks for the hint. I declared my types in types.bif and defined them in types.bro now, but now I can’t acces them anymore in my Source.cc file. I get following error:

error: ‘BifType::Record::My\_Type’ has not been declared

My .cc line: rl = new RecordVal(BifType::Record::My\_Type);

How can I access the types now?

P.S. Yeah, I think the other mailing list is besser for this purpose, but I don’t want to start a new question now. 🙂

Make sure you include the generated header file in your .cc file like this…

#include “types.bif.h”
