LR中exit(-1)、return -1/return 0等的区别

实验环境：LR11：
代码：

• vuser_init

vuser_init()
{
	lr_output_message(">>>>>>>>>> init");
	//exit(-1);
	//return -1;
	return 0;
}

• Action1

Action1()
{
	lr_output_message(">>>>>>>>>>> 1");
	//exit(-1);
	//exit(-2);
	//exit(0);
	//exit(1);
	//return -1;
	//return 0;
	//return 1;
	lr_output_message(">>>>>>>>>>> 2");
	return 0;
}

• Action2

Action2()
{
	lr_output_message(">>>>>>>>>>> 3");
	return 0;
}

• vuser_end

{
	lr_output_message(">>>>>>>>>>> end");
	return 0;
}

直接运行，结果如下

Starting action vuser_init.

一、当在Action1中加上 exit(-1),后直接终止迭代停止程序运行，后续代码均不执行

Action1()
{
	lr_output_message(">>>>>>>>>>> 1");//执行 >>>>>>>>>>> 1
	exit(-1); // 程序直接终止,跳出所有迭代和`Action`
	lr_output_message(">>>>>>>>>>> 2");//不执行
	return 0;
}

注：exit(0)/exit(-2)/exit(2)/exit(1) 也是一样的

二、当在Action1中加上return -1时,程序执行到此处，跳出所有Action和迭代,但会执行vuser_end。

Action1()
{
	lr_output_message(">>>>>>>>>>> 1");//执行 >>>>>>>>>>> 1
	return -1;; // 程序跳出所有迭代和`Action`，但会执行 vuser_end
	lr_output_message(">>>>>>>>>>> 2");//不执行
	return 0;
}

三、当在Action1中加上return 0时,程序执行到此处，仅跳出当前Action，当前Action中后续代码不执行。

Action1()
{
	lr_output_message(">>>>>>>>>>> 1");//执行 >>>>>>>>>>> 1
	return 0;; // 程序仅跳出当前`Action`，后续代码不执行，其他Action和迭代正常执行
	lr_output_message(">>>>>>>>>>> 2");//不执行
	return 0;
}
