After adding the line:
if (fp==NULL)
{
printf("error, NULL pointer!\n");
return(1);
}
and then rebuilding the code, everything worked. But it's strange that if I
delete that code segment and never check whether the fp pointer is NULL or
not, I always get a segmentation fault. Can this be some kind of an
optimization problem? I don't know why it happens. Thank you for the
comments.
