  void abort(void);

  

abort() terminates the program. It does the following (in this order):

• raises signal SIGABRT
• flushes all open output streams
• closes all open files
• removes all temporary files
• calls HALT

If your application handles SIGABRT and the signal handler does not return (e.g., because it does a longjmp()), the application is not halted.
