NAME

std::filesystem::filesystem_error::path1,std::filesystem::filesystem_error::path2 - std::filesystem::filesystem_error::path1,std::filesystem::filesystem_error::path2

Synopsis

const std::filesystem::path& path1() const noexcept; (since C++17)
const std::filesystem::path& path2() const noexcept; (since C++17)

Returns the paths that were stored in the exception object.

Parameters

(none)

Return value

References to the copy of the path parameters stored by the constructor.

Example

// Run this code

#include <cstdio>
#include <filesystem>
#include <iostream>

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"
