LR中exit(-1)、return -1/return 0等的區別

實驗環境：LR11：
代碼：

• 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;
}

直接運行，結果如下

Starting action vuser_init.

一、當在Action1中加上 exit(-1),後直接終止迭代停止程序運行，後續代碼均不執行

Action1()
{
	lr_output_message(">>>>>>>>>>> 1");//執行 >>>>>>>>>>> 1
	exit(-1); // 程序直接終止,跳出所有迭代和`Action`
	lr_output_message(">>>>>>>>>>> 2");//不執行
	return 0;
}

Action1.c(3): >>>>>>>>>>> 1 

注：exit(0)/exit(-2)/exit(2)/exit(1) 也是一樣的

二、當在Action1中加上return -1時,程序執行到此處，跳出所有Action和迭代,但會執行vuser_end。

Action1()
{
	lr_output_message(">>>>>>>>>>> 1");//執行 >>>>>>>>>>> 1
	return -1;; // 程序跳出所有迭代和`Action`，但會執行 vuser_end
	lr_output_message(">>>>>>>>>>> 2");//不執行
	return 0;
}

三、當在Action1中加上return 0時,程序執行到此處，僅跳出當前Action，當前Action中後續代碼不執行。

Action1()
{
	lr_output_message(">>>>>>>>>>> 1");//執行 >>>>>>>>>>> 1
	return 0;; // 程序僅跳出當前`Action`，後續代碼不執行，其他Action和迭代正常執行
	lr_output_message(">>>>>>>>>>> 2");//不執行
	return 0;
}
