mkstemp opens the temporary file, which is not much use if you want to run 
an external program which requires a filename.

To solve the potential race conditions with creating temporary files, I 
think the right solution is to use mkdtemp(3) instead. That creates and 
returns the name of a temporary directory. Now you are free to create as 
many files (and subdirectories) as you like with whatever names you like 
within that, secure in the knowledge that nobody else can interfere with 
you.
