你如何在C中获得目录列表？

#include<stdio.h>
#include <dirent.h>

int main() {
    DIR *dir;
    struct dirent *entry;

    dir = opendir(".");
    if (dir == NULL) {
        printf("无法打开目录\n");
        return 1;
    }

    while ((entry = readdir(dir)) != NULL) {
        printf("%s\n", entry->d_name);
    }

    closedir(dir);
    return 0;
}
