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.

Most programs will create temp files in a folder called C:\Users\AppData\Local\Temp — that's likely where your computer stores the majority of your temporary files.
The /tmp directory is a temporary landing place for files. Users also have write access to this directory, which can be a bad thing, but there is a solution.
Check following variables:
TMPDIR 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.
