# std::experimental::filesystem::space_info

From cppreference.com
< cpp‎ | experimental‎ | fs

Defined in header `<experimental/filesystem>` |  |
struct space_info { uintmax_t capacity; uintmax_t free; uintmax_t available; }; |  | (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
