Question about excuting action sharpfuzz/src/SharpFuzz/Fuzzer.LibFuzzer.cs about sharpfuzz HOT 1 CLOSED

Hi @gfarida!

What is data here? And why don't you work with stream like this:

afl-fuzz passes the input data using the standard input, while my libFuzzer driver is using shared memory. You can see how it's implemented here:

https://github.com/Metalnem/libfuzzer-dotnet/blob/master/libfuzzer-dotnet.cc#L204

And second question: I can not find place (in sharpfuzz for windows) where you fill bitmap with run information. Can you show me it?

If I understand the question correctly, it's these four lines (for both Windows and Posix):

https://github.com/Metalnem/sharpfuzz/blob/master/src/SharpFuzz/Fuzzer.LibFuzzer.cs#L40

FuzzerIpc constructor reads the ID of the shared memory segment where trace bitmap is located, and then TraceWrapper is created on that segment and filled by SharpFuzz.
