std::experimental::filesystem::temp_directory_path
Min standard notice:
Header: <experimental/filesystem>
Returns the directory location suitable for temporary files.
# Declarations
path temp_directory_path();
path temp_directory_path( error_code& ec );
(filesystem TS)
# 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 <experimental/filesystem>
#include <iostream>
namespace fs = std::experimental::filesystem;
int main()
{
std::cout << "Temp directory is " << fs::temp_directory_path() << '\n';
}
