Thread: how to use atexit()??

the description of at exit is as follows, can somone give me an example of how it is used??

int atexit( void (*func)(void) );

The atexit function will call a chosen function at the end of a program, the nice thing about this function is that it will call something useful such as garbage collection and saving routines even if you abort by way of exit().

Code:

#include <stdio.h>
#include <stdlib.h>

void end( void )
{ 
  printf ( "The end function was called\n" ); 
}
        
int main ( void )
{
  atexit ( end );
  printf ( "Normal processing\n" );
  return EXIT_SUCCESS;
}
