【c++基础】c++创建文件夹

code

if (mkdir(finalpath.c_str(), S_IRWXU | S_IRWXG | S_IROTH | S_IXOTH) == -1)
{
    if( errno == EEXIST ) {
       // alredy exists
    } else {
       // something else
        std::cout << "cannot create sessionnamefolder error:" << strerror(errno) << std::endl;
    }
}

need to include <sys/stat.h> for S_IRWXU, S_IRWXG；
