我想从默认安装目录访问所有目录和子目录,但它在遍历文件夹时失败。这里我将路径传递给常量char。下面是代码
using namespace std;
int reading(const char *d_path)
{
cout << "In Reading" << endl;
/* bfs::path pathSource("c:\\Program Files\\"); */
struct stat info; //
DIR *dir;
struct dirent *ent;
dir = opendir(d_path);
cout << dir << endl;
if ((dir = opendir(d_path)) != NULL)
{
cout << "in IF" << endl;
while ((ent = readdir (dir)) != NULL)
{
if (ent->d_name[0] != NULL)
{
cout << "New" << endl;
string path = string (d_path) + string(ent->d_name) + '\\';
cout << "Entry = " << path << endl;
stat (path, &info);
if(S_ISDIR(info.st_mode))
{
reading(path);
}
}
}
closedir(dir);
}
/* Print all the files and directories within directory */
else
{
/* Could not open directory */
perror("");
}
return 0;
}

使用
string::c_str()
方法,如stat(path.c_str())
,将C++字符串转换为C字符串。更多信息请参见 std::string::c_str。
