将文本信息从Windows命令解释器（cmd.exe）传递到字符数组

Question

有没有一种方法可以从Windows命令解释器（cmd.exe）提取文本信息到字符数组，而无需从命令解释器创建文本文件？

Answer 1

Try _popen ( <stdio.h> ), the Microsoft's version of the POSIX popen function:

#include <stdio.h>
#include <iostream>
#include <string>

using namespace std;

int main(void) {
    FILE * pp;
    char buf[1024];
    string result;

    if ((pp = _popen("dir", "r")) == NULL) {
        return 0;
    }

    while (fgets(buf, sizeof(buf), pp)) {
        result += buf;
    }

    _pclose(pp);

    cout << result << endl;

    return 0;
}
