No, there is no portable function because there is no portable
notion of "user temporary directory". However, you could try
'getenv("TEMP")' or 'getenv("TMP")'. RTFM about it.

Alberto,

As Victor says c++ has no notion of a temporary file directory, but if
you just want to create a temporary file the the C library's stdio
header provides the function tmpfile():
http://www.cplusplus.com/reference/clibrary/cstdio/tmpfile.html

TMPDIR is what Posix recommends, I think.
