Design of FreeType 2
IntroductionThis document provides the design and implementation details of the FreeType 2 function library. The goal of this document is to allow developers to better understand how FreeType 2 is organized and to allow them to expand, customize, and debug it.First, let's first understand the purpose of this database, that is, why the databas

learning the concept and solution of the anomaly, I think there is a difference between the exception and the error, why the error cannot be handled in a way that solves the exception.
Question 1 Solution: the study questions of the textbook has learned the difference between errors and anomalies:Exception: An object that defines an informal situation or error that is thrown by a program or run-time environment and can be captured and processed as needed.Error: The error is similar to an ex

I wrote it in C # + WPF. If I use a callback function, errors always occur. It should be a matter of hosting and non-hosting. After reading the source code of SharpPcap, it seems that there is no good solution.
