(filesystem TS)

Represents the filesystem information as determined by space .

The members have the following meaning:

  • capacity -- total size of the filesystem, in bytes
  • free -- free space on the filesystem, in bytes
  • available -- free space available to a non-privileged process (may be equal or less than free )

Example

Run this code 
#include <experimental/filesystem>
#include <iostream>
namespace fs = std::experimental::filesystem;
int main()
{
    fs::space_info devi = fs::space("/dev/null");
    fs::space_info tmpi = fs::space("/tmp");
    std::cout << "         Capacity         Free    Available\n"
              << "/dev:   " << devi.capacity << "   "
              << devi.free << "   " << devi.available << '\n'
              << "/tmp: " << tmpi.capacity << ' '
              << tmpi.free << ' ' << tmpi.available << '\n';
}

Possible output: 

          Capacity         Free    Available
/dev:   4175114240   4175110144   4175110144
/tmp: 420651237376 411962273792 390570749952
