[edit] Example
Run this code
#include #include #include int main() { const std::filesystem::path old_p{std::tmpnam(nullptr)}, new_p{std::tmpnam(nullptr)}; try { std::filesystem::rename(old_p, new_p); // throws since old_p does not exist } catch(std::filesystem::filesystem_error const& ex) { std::cout << "what(): " << ex.what() << '\n' << "path1(): " << ex.path1() << '\n' << "path2(): " << ex.path2() << '\n'; } }
Possible output:
what(): filesystem error: cannot rename: No such file or directory [/tmp/fileIzzRLB] [/tmp/fileiUDWlV] path1(): "/tmp/fileIzzRLB" path2(): "/tmp/fileiUDWlV"
