*Returns:* An unspecifed directory path suitable for temporary files. An
|
| 9 |
+
error shall be reported if `!exists(p) || !is_directory(p)`, where `p`
|
| 10 |
+
is the path to be returned. The signature with argument `ec` returns
|
| 11 |
+
`path()` if an error occurs.
|
| 12 |
+
|
| 13 |
+
*Throws:* As specified in [[fs.err.report]].

[*Example 1*: For POSIX-based operating systems, an implementation
|
| 16 |
+
might return the path supplied by the first environment variable found
|
| 17 |
+
in the list TMPDIR, TMP, TEMP, TEMPDIR, or if none of these are found,
|
| 18 |
+
`"/tmp"`. For Windows-based operating systems, an implementation might
|
| 19 |
+
return the path reported by the Windows `GetTempPath` API
|
| 20 |
+
function. — *end example*]
