std::experi...ace_filename(3) C++ Standard Libarystd::experi...ace_filename(3)

NAME
       std::experimental::filesystem::path::replace_filename - std::experimen-
       tal::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"
