我有一个需要编译为64位的程序。我有另一个需要编译为32位的 程序，并将调用64位二进制文件。有没有办法让64位二进制文件将字符串返回到32位的？如果是这样，怎么样？ 我能想到的唯一方法就是让32位二进制调用64- 位二进制，然后写到一个文本文件，最后有32位 二进制文件读取它。 有更好的方法吗？
I have a program that needs to be compiled as 64bit. I have another program that needs to be compiled as 32bit and will call that 64-bit binary. Is there a way for the 64-bit binary to return a string to the 32-bit? If so, how? The only way I could think of is to have the 32-bit binary call the 64- bit binary, then it writes to a text file and finally have the 32-bit binary read it off. Is there a better way to do this?

32位二进制文件是否支持多长？如果不是，你可能需要按照你写的 来做，或者使用一些非便携式的方法，比如popen（），或者通过套接字调用 64位并读取从标准输出中回来字符串。 但当然所有这些都是偏离主题的:-)。 - 问候， Stan Milam =========================== ======================= =========== 平庸吉他协会的特许会员上演 昂贵的乐器有限公司 =========================== ======================= ===========
Does the 32 bit binary support long long? If not you may have to do as you wrote, or use some non-portable means such as popen(), or invoke the 64 bit via a socket and read back the string from its standard output.

嗨Stan， 我不擅长C.如果支持很长时间怎么办？什么是 更有效的方式呢？我会使用什么样的函数 为你建议调用套接字的第二种方法？ 谢谢！ :)
Hi Stan, I''m not good in C. What if it supports long long? What would be the more efficient way of doing it? What sort of functions would I use for the second method you suggested with invoking a socket? Thanks! :)

Google for IPC，套接字是恕我直言最好的。打开一个端口0的套接字 和 将给定的端口号传递给被叫方。但是你需要先了解 IPC 来理解上面的句子。
Google for IPC, sockets are IMHO the best. Open a socket with port 0 and pass the given port number to the callee. But you need to learn about IPC first to understand the sentence above.
