NAME

std::experimental::filesystem::path::replace_filename - std::experimental::filesystem::path::replace_filename

Synopsis

path& replace_filename( const path& replacement ); (filesystem TS)

Replaces a single filename component with replacement.

Equivalent to the following:

remove_filename();
operator/=(replacement);

The behavior is undefined if the path has no filename component (has_filename
returns false).

Parameters

(none)

Return value

*this

Exceptions

May throw implementation-defined exceptions.

Example

// Run this code

#include <iostream>
#include <experimental/filesystem>
namespace fs = std::experimental::filesystem;

int main()
{

std::cout << fs::path("/foo").replace_filename("bar") << '\n'
<< fs::path("/").replace_filename("bar") << '\n';
}

Output:

"/bar"
"bar"
