PenTool | Pen tool - This project is a canvas-based path drawing tool | Editor library

I have a C program that uses SDL2. I had a working program when the contents of PenTool were not in a function and were instead where the function is called, however putting it into a function has caused an issue I cannot get my head around. Avoiding global variables, I have passed all the variables I need to manipulate by reference including the function within PenTool, bresline. The code is supposed to draw a continuous line from the mouse by making the current mouse coords the end point and the previous mouse coords the start point of a line. However, in this functional layout, current mouse coords are recognized and drawn correctly on the screen, but previous mouse coords stay the same, resulting in every line drawn starting from the same point, instead of the actual previous mouse position. Furthermore, the print function shows all variables as unchanging while the mouse is moving, despite the running program drawing where my mouse is.

The issue is with bresline. When I comment it out, the print function shows all the variables updating correctly with mouse movement, so could someone please explain why bresline is preventing previous mouse coords from being assigned properly, and why it's preventing printf from showing correct mouse coords.

I have looked at other questions on StackOverflow and elsewhere on proper passing by reference and from what I can tell, I have passed my variables correctly and I don't know how to read C++/Java so those answers don't help, so I really don't know where I am going wrong.

i would like to ask a question about a problem that i have for the last couple days. First of all i am a beginner in machine learning and this is my first time using the XGBoost algorithm so excuse me for any mistakes I have done.

I trained my model to predict whether a log file is malicious or not. After i save and reload my model on a different session i use the predict function which seems to be working normally ( with a few deviations in probabilities but that is another topic, I know I, have seen it in another topic )

The problem is this: Sometimes when i try to predict a "small" csv file after load it seems to be broken predicting only the Zero label, even for indexes that are categorized correct previously. For example, i load a dataset containing 20.000 values , the predict() is working. I keep only the first 5 of these values using pandas drop, again its working. If i save the 5 values on a different csv and reload it its not working. The same error happens if i just remove by hand all indexes (19.995) and save file only with 5 remaining.

I would bet it is a size of file problem but when i drop the indexes on the dataframe through pandas it seems to be working Also the number 5 ( of indexes ) is for example purpose the same happens if I delete a large portion of the dataset. I first came up with this problem after trying to verify by hand some completely new logs, which seem to be classified correctly if thrown into the big csv file but not in a new file on their own.

I have a edit photo php script that i want to load in my iOS app. I am calling it through WebView "www.example/com/myTool". When the edit task is complete the webView is moving to homepage of the website. I want when the Edit task is complete then instead of redirecting url to www.example.com/home the webView closes and it moves back to View Controller.

What i can think of solution is - when the URL of webView changes then the webView should close and move back to view controller .. But i don't know how to apply it in code.

I tried to do interaction between paper.js and typescript.

So I want to write some event handlers into constractor of PenTool. (because I want to use DI and define all paper-events while tool is creating)

I have next wrap of code:
