NAME¶
std::experimental::filesystem::temp_directory_path - std::experimental::filesystem::temp_directory_path
Synopsis¶
Defined in header <experimental/filesystem>
path temp_directory_path(); (1) (filesystem TS)
path temp_directory_path( error_code& ec );
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¶
The overload that does not take a error_code& parameter
throws filesystem_error on
underlying OS API errors, constructed with path to be returned as the first
argument
and the OS error code as the error code argument. std::bad_alloc may be
thrown if
memory allocation fails. The overload taking a error_code& parameter sets
it to the
OS API error code if an OS API call fails, and executes ec.clear() if no
errors
occur. This overload has
noexcept specification:
noexcept
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¶
// Run this code
#include <iostream>
#include <experimental/filesystem>
namespace fs = std::experimental::filesystem;
int main()
{
std::cout << "Temp directory is " <<
fs::temp_directory_path() << '\n';
}
Possible output:¶
Temp directory is "C:\Windows\TEMP\"
