[lttng-dev] Creating a CTF-File

[Andre Bette]

Hi everyone,
I have a question about the concept of the CTF data types implementation.

I want to write the packet header and context.

Example:

BinaryCTFWriter writer = new BinaryCTFWriter("F:/kernel"); // Class from 
the Javeltrace Project


writer.openStream(0);

PacketInfo packet = new PacketInfo(0,?,?) ;     //PacketInfo(int 
steamID,StructDefinition header, StructDefinition context)

writer.openPacket(packet);

...

How do I create the data(Timestamp begin , Timestamp end etc.) for the 
header and context? I dont understand the concept of 
StructDefinition/StructDeclaration. Do I need a metadata file for this ? 
Or can I write it later ?




Best Regards,

Andre
