std::filesystem::temp_directory_path

Since C++17

Header: <filesystem>

Returns the directory location suitable for temporary files.

# Declarations

path temp_directory_path();

(since C++17)

path temp_directory_path( std::error_code& ec );

(since C++17)

# Return value

A directory suitable for temporary files. The path is guaranteed to exist and to be a directory. The overload that takes error_code& argument returns an empty path on error.

# Notes

On POSIX systems, the path may be the one specified in the environment variables TMPDIR, TMP, TEMP, TEMPDIR, and, if none of them are specified, the path “/tmp” is returned.

On Windows systems, the path is typically the one returned by GetTempPath.

# Example

#include <filesystem>
#include <iostream>
namespace fs = std::filesystem;
 
int main()
{
    std::cout << "Temp directory is " << fs::temp_directory_path() << '\n';
}
