Can anyone tell me how to find a specific sequence in a binary file? I could do it myself but not only would it take forever it would be the incorrect most processor maxing and super taxing way. I'd really appreicate your help. Even if its just the command with no explaination, I can look it up and research it myself. I'm not trying to get anyone to write the code for me.

The naive approach would be to read the contents of the file and use memcmp or similar. What code are you using now?
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
I haven't got one, I want to know what the right thing to do is so that I can build it properly. Thats why I didn't post any code.
Give it a go, and if you run into any problems just post the code you're having trouble with, along with compile errors, expected results, etc.
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
Arbitrary binary data searching isn't any different from searching in strings, so String Search Algorithms apply.
All the buzzt!
