struct space_info { std::uintmax_t capacity; |
(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 thanfree
)
Example
Run this code
#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
