# std::filesystem::temp_directory_path

 Defined in header  path temp_directory_path(); path temp_directory_path( std::error_code& ec ); (1) (since C++17)

Returns the directory location suitable for temporary files.

## Contents

(none)

### 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.

### Exceptions

The overload that does not take a parameter throws filesystem::filesystem_error on underlying OS API errors, constructed with path to be returned as the first path argument and the OS error code as the error code argument. The overload taking a parameter sets it to the OS API error code if an OS API call fails, and executes ec.clear() if no errors occur. Any overload not marked noexcept may throw std::bad_alloc if memory allocation fails.

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

Possible output:

Temp directory is "C:\Windows\TEMP\"
