我正在编写一个批处理模拟器作为个人项目。我正在尝试使用 unistd.h 中的 chdir() 来实现 cd 命令。但是,使用它会导致段错误。
主.cpp:
#include <cstdlib>
#include <iostream>
#include <string>
#include <vector>
#include <stdio.h>
//Custom headers
#include "splitting_algorithm.hpp"
#include "lowercase.hpp"
#include "chdir.hpp"
//Used to get and print the current working directory
#define GetCurrentDir getcwd
using namespace std;
int main(int argc, char* argv[])
{
string command;
//Begin REPL code
while (true)
{
//Prints current working directory
cout<<cCurrentPath<<": ";
std::getline(std::cin, command);
vector<string> tempCommand = strSplitter(command, " ");
string lowerCommand = makeLowercase(string(strSplitter(command, " ")[0]));
//Help text
if(tempCommand.size()==2 && string(tempCommand[1])=="/?")
{
cout<<helpText(lowerCommand);
}
//Exit command
else if(lowerCommand=="exit")
{
return 0;
}
else if(lowerCommand=="chdir")
{
cout<<string(tempCommand[1])<<endl;
chdir(tempCommand[1]);
}
else
cout<<"Can't recognize \'"<<string(tempCommand[0])<<"\' as an internal or external command, or batch script."<<endl;
}
return 0;
}
chdir.cpp:
#include <cstdlib>
#include <string>
#include <unistd.h>
void chdir(std::string path)
{
//Changes the current working directory to path
chdir(path);
}
奇怪的是,使用 cout 获取 chdir 的路径工作得非常好。我该如何解决?
