如何传递一个向量到execvp [英] How to pass a vector to execvp

问题描述

我想传递一个向量作为execvp的第二个参数。可能吗？

I want to pass a vector in as the second argument to execvp. Is it possible?

推荐答案

不直接;你需要将向量表示为一个NULL终止的字符串指针数组。如果它是一个字符串的向量，这是直接做;如果它是一些其他类型的数据，你将不得不说明如何将其编码为字符串。

Not directly; you'd need to represent the vector as a NULL-terminated array of string pointers somehow. If it's a vector of strings, that is straightforward to do; if it's some other kind of data you would have to figure how to encode it as strings.
