std::filesystem::path::replace_filename
std::filesystem::path::replace_filename
path& replace_filename( const path& replacement ); | (since C++17) |
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
(none).
Example
#include <iostream>
#include <filesystem>
namespace fs = std::filesystem;
int main()
{
std::cout << fs::path("/foo").replace_filename("bar") << '\n'
<< fs::path("/").replace_filename("bar") << '\n';
}Output:
"/bar" "bar"
