std::experimental::filesystem::path::remove_filename

< cpp‎ | experimental‎ | fs‎ | path
path& remove_filename()
 (1) (filesystem TS)

Removes a single filename component.

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

Parameters

Return value

*this

Exceptions

May throw implementation-defined exceptions.

Example

#include <iostream>
#include <experimental/filesystem>
namespace fs = std::experimental::filesystem;
 
int main()
{
 
    std::cout << fs::path("/foo").remove_filename() << '\n'
              << fs::path("/").remove_filename() << '\n';
}

Output:

"/"
""
