Hi,

I'm developing a dynamic preprocessor by DPX. After processing a packet, I
might generate an alert and log that packet for later analyzing if I found
it abnormal.

My problem:
I found 2 member of DynamicPreprocessorData struct: alertAdd and
genSnortEvent. I supposed those could help me. But I dont understand the
difference between 2 member yet. Which of them should I choose for my
purpose? If you know any other way, feel free to raise your idea.

Use alertAdd() to raise the alert.  Check dpx.c for an example.

BRs,
