glutinit参数 [英] glutinit arguments

问题描述

我是openGL的初学者.在所有简单示例中，main函数都有参数，而glutinit func使用这些参数.但是我不明白为什么他们是必要的.我没有在命令参数中写任何内容，并且程序仍然可以正常工作.它们是用来干什么的?你能举个例子吗?

I am beginner at openGL. In all simple examples main function has arguments and glutinit func uses those. But I don't understand why they are necessary. I write nothing in command arguments and the programs still works. What are they used for? Can you give an example?

glutInit(&argc, argv)

推荐答案

使用它们是为了使GLUT可以处理命令行参数.它具有许多始终使用的参数.如果您不希望GLUT处理参数，则只需传递如下内容:

They're used so that GLUT can process command line arguments. It has a number of arguments that it always uses. If you don't want GLUT to process arguments, just pass something like this:

{
  int argc = 1;
  char *argv[1] = {(char*)"Something"};
  glutInit(&argc, argv);
}
