abort

abort - cause abnormal program termination

#include <stdlib.h>
 void abort(void);

The R abort () function causes abnormal program termination unless the signal SIGABRT is caught and the signal handler does not return. If the R abort () function causes program termination, all open streams are closed and flushed.

If the SIGABRT signal is blocked or ignored, the R abort () function will still override it.

The R abort () function never returns.
