std::filesy...ectory_path(3) C++ Standard Libary std::filesy...ectory_path(3) NAME std::filesystem::temp_directory_path - std::filesystem::temp_direc- tory_path Synopsis Defined in header <filesystem> path temp_directory_path(); (1) (since C++17) path temp_directory_path( std::error_code& ec ); (2) (since C++17) Returns the directory location suitable for temporary files. Parameters (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 Any overload not marked noexcept may throw std::bad_alloc if memory allocation fails. 1) Throws std::filesystem::filesystem_error on underlying OS API er- rors, constructed with path to be returned as the first path argument and the OS error code as the error code argument. 2) Sets a std::error_code& parameter to the OS API error code if an OS API call fails, and executes ec.clear() if no errors occur. Notes On POSIX systems, the path may be the one specified in the environ- ment 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 Get- TempPath. Example // Run this code #include <filesystem> #include <iostream> namespace fs = std::filesystem; int main() { std::cout << "Temp directory is " << fs::temp_directory_path() << '\n'; } Possible output: Temp directory is "C:\Windows\TEMP\" See also tmpfile creates and opens a temporary, auto-removing file (function) current_path returns or sets the current working directory (C++17) (function) http://cppreference.com 2024.06.10 std::filesy...ectory_path(3)
