从C转换为C ++ ---中断例程问题==>中断远 [英] Converting from C to C++ --- Having Issue with interrupt routine ==> interrupt far
问题描述
我有一个用C编写的应用程序。它仅适用于WIN 32位，我们决定将代码转换为C ++，以便在64位Windows机器上使用它。
I have an application written in C. It works only on WIN 32 bit and we decide to convert the code to C++ in order to use it on 64 bit Windows Machine as well.
转换代码后我得到的第一个错误是以下错误。
The first error that I've got after converting my code was the following one.
/ **** *********************************** /
/ *串行例程变量定义* / b
/ *************************************** /
$
/ *这些指针存储原始中断向量

/***************************************/
/* Serial routine variable definitions */
/***************************************/
/* these pointers store the original interrupt vectors
for the com ports */
static void（interrupt far * org_empcom_vector）（void）;   //错误行
static void (interrupt far *org_empcom_vector)(void); // error line
错误 5
错误C4430：缺少类型说明符 - 假设为int。注意：C ++不支持default-int
c：\ usersrs \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ consoleapplication5\consoleapplication5 \consoleapplication5.cpp
676 1
ConsoleApplication5
Error 5
error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
c:\users\me\documents\visual studio 2013\projects\consoleapplication5\consoleapplication5\consoleapplication5.cpp

ConsoleApplication5
因此，我意识到C ++中的中断例程与C不同。
Therefore, I realized that interrupt routine in C++ is different than C.
我上网查找解决方法。最后，我最终得到了以下几行代替。
I surfed the net to find a workaround for this. Eventually, I was ended up with the following lines to replace.
void _interrupt（...）
{
void * org_empcom_vector（void）;
void * org_meter_vector（void）;
}
void _interrupt(...)
{
void *org_empcom_vector(void);
void *org_meter_vector(void);
}
因此，Visual Studio出现了以上更换没有错误。但是，我并不完全确定这是否是定义中断向量的正确方法。
So, Visual Studio came up with no error with the above replacement. However, I am not entirely too sure that this is the right way to define interrupt vectors or not.
所以，我想让你就此与我分享你的看法。谢谢，麻烦您了！ ：）
So, I want you to share your opinion with me on this. Please and thank you! :)
推荐答案
为什么您认为需要将代码编译为C ++而不是C代表64位系统？
Why do you think you need to compile code as C++ instead of C for a 64 bit system?
