std::filesystem::operator/(std::filesystem::path)

path operator/( const path& lhs, const path& rhs );

Concatenates two path components using the preferred directory separator if appropriate (see operator/= for details).

Effectively returns path(lhs) /= rhs.

This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::filesystem::path is an associated class of the arguments. This prevents undesirable conversions in the presence of a using namespace std::filesystem; using-directive.

Parameters

Return value

The result of path concatenation.

Example

#include <iostream>
#include <filesystem>
namespace fs = std::filesystem;
int main() {
    fs::path p = "C:";
    std::cout << "\"C:\" / \"Users\" / \"batman\" == "
              << p / "Users" / "batman" << '\n';
}

"C:" / "Users" / "batman" == "C:Users\\batman"
