std::experimental::filesystem::space_info (3) - Linux Man Pages

std::experimental::filesystem::space_info: std::experimental::filesystem::space_info

NAME

std::experimental::filesystem::space_info - std::experimental::filesystem::space_info

Synopsis


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


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 <iostream>
  #include <experimental/filesystem>
  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
