Defined in header
Causes abnormal program termination unless SIGABRT is being caught by a signal handler passed to signal and the handler does not return.
Functions passed to atexit() are not called. Whether open resources such as files are closed is implementation defined. Implementation defined status is returned to the host environment that indicates unsuccessful execution.
