| (since C++17) |
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) #include <iostream>
#include <filesystem>
namespace fs = std::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
