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/c...o/tmpfile.html

HTH,

TMPDIR is what Posix recommends, I think.
