Use a dynamically generated delegate to Improve the Performance of calling a dynamic assembly

Preface In some cases, we need to dynamically generate a function, for example, the C # program for function graphics (simplified version) mentioned in an article recently published by Galaxy. Not long ago, our great old zhao also sent an article titled direct call of methods, reflection call and ...... Lambda expression call, he also recommends dynamic reflection library, but I don't know how to apply it here, because the input here is a string. I used codedom to implement it myself (in fact, I

Detailed description of user and core states, process switching, and system calling principles

Detailed description of user and core states, process switching, and system calling principles1) Example void testfork(){ if(0 = = fork()){ printf(“create new process success!\n”); } printf(“testfork ok\n”); } This code is very simple.
