c++ - How do I find the 'temp' directory in Linux?

Question

How do I find the 'temp' directory in Linux? I am writing a platform neutral C++ function that returns the temp directory. In Mac and Windows, there is an API that returns these results. In Linux, I'm stumped. ----------------------------------------

Answer 1

Check following variables:

• The environment variable TMPDIR
• The value of the P_tmpdir macro

If all fails try to use the directory /tmp.

You can also use tempnam function to generate a unique temporary file name.
