get temp directory

[Alberto Bignotti]

How to get user temporany directory from c++ function?

example:

string myTempDir = getTempDir();

now myTempDir contains 'c:\tmp'

is there a portable function?

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

HTH,

TMPDIR is what Posix recommends, I think.
