What Moritz is saying is that the following implementation of fclose
is correct according to the C standard:
int fclose(FILE *stream){
if(stream == NULL){
return go_wild_and_corrupt_all_the_memory();
}else{
return actually_close_the_file(stream);
}
}
I think we can correctly assume no fclose implementations exist that
do anything but access data pointed at by stream. Which means a
segfault on every platform we support.
On platforms that may not segfault, you'd be on your own.
In other words, I think we can assume for any C functions that are
passed pointers that dereference those pointers, passing null is
safely going to segfault.
I'm not going to assume that.
Tell you what, when you find a D platform that this doesn't happen, we
can fix it with a version statement ;)
