* Selection of a file name for a temporary file.
* This is system-dependent!
*
* The code as given is suitable for most Unix systems, and it is easily
* modified for most non-Unix systems. Some notes:
* 1. The temp file is created in the directory named by TEMP_DIRECTORY.
* The default value is /usr/tmp, which is the conventional place for
* creating large temp files on Unix. On other systems you'll probably
* want to change the file location. You can do this by editing the
* #define, or (preferred) by defining TEMP_DIRECTORY in jconfig.h.
*
* 2. If you need to change the file name as well as its location,
* you can override the TEMP_FILE_NAME macro. (Note that this is
* actually a printf format string; it must contain %s and %d.)
* Few people should need to do this.
*
* 3. mktemp() is used to ensure that multiple processes running
* simultaneously won't select the same file names. If your system
* doesn't have mktemp(), define NO_MKTEMP to do it the hard way.
* (If you don't have <errno.h>, also define NO_ERRNO_H.)
*
* 4. You probably want to define NEED_SIGNAL_CATCHER so that cjpeg.c/djpeg.c
* will cause the temp files to be removed if you stop the program early.
