Thread: return or exit

Code:

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

int main(void)
{
 float light[3][3];
 FILE *Input;


     Input = fopen("bunny2.mtl","rb");
     if(Input==NULL)
     {
      fprintf(stderr,"Cannot find bunny2.mtl file.\n");
      exit(-1);   //Exit
      return -1; //Exit
     }
     
     fclose(Input);

 return 0;
}

In small programs like the above which is the best way to exit after an error ?
return or exit() or it doesn't matter which one to choose ?

Thank you

Actually, when there is an error abort() is for panicking, my vote would be for exit().
