                    |   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 <experimental/filesystem> #include <iostream> 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"
