/** TEMP FILE SUPPORT
**
** simple interface to create an empty temporary file on the system.
**
** create the file with tempfile_create(), which returns a reference to a TempFile
** object, or NULL if your system is so weird it doesn't have a temporary directory.
**
** you can then call tempfile_path() to retrieve the TempFile's real path to open
** it. the returned path is owned by the TempFile object and should not be freed.
**
** all temporary files are destroyed when the program quits, unless you explicitely
** close them before that with tempfile_close()
**/

/** TEMP FILE CLEANUP
**
** We delete all temporary files in atexit()-registered callbacks.
** however, the Win32 DeleteFile is unable to remove a file unless
** all HANDLEs to it are closed in the terminating process.
**
** Call 'atexit_close_fd' on a newly open-ed file descriptor to indicate
** that you want it closed in atexit() time. You should always call
** this function unless you're certain that the corresponding file
** cannot be temporary.
**
** Call 'atexit_close_fd_remove' before explicitely closing a 'fd'
