Ends program execution immediately

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

The abort( ) function terminates execution of a program by raising the SIGABRT signal.

For a "clean" program termination, use the exit( ) function. abort( ) does not flush the buffers of open files or call any cleanup functions that you have installed using atexit( ). The abort( ) function generally prints a message such as:

Abnormal program termination

on the stderr stream. In Unix, aborting a program also produces a core dump.

Example

struct record { long id;
                int data[256];
                struct record *next;
              };
/* ... */
struct record *new = (struct record *)malloc( sizeof(struct record) );
if ( new == NULL )            // Check whether malloc failed!
{
  fprintf( stderr, "%s: out of memory!", _  _func_  _ );
  abort( );
}
else /* ... */
