struct space_info{ uintmax_t capacity; | (filesystem TS) | |
Represents the filesystem information as determined byspace.
The members have the following meaning:
capacity -- total size of the filesystem, in bytesfree -- free space on the filesystem, in bytesavailable -- free space available to a non-privileged process (may be equal or less thanfree)#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
