Weird huh? - what does fopen return? - Dr.Einstein - 14.11.2012
This isn't important, but if you know about it, enlighten us.
If you try:
Код:
new File:f;
f=fopen("ss.txt",io_read);
printf("%d",f);//you will get a warning here..
On the other hand, if you try this:
Код:
printf("%d",fopen("ss.txt",io_read));
The same thing is for all file modes..
Why?

Just a value to identify the file in other functions. Why do you care anyway?
I also think the value is somehow determined from the current time, to make sure it is different at all times.

It's a good thing to know about functions that you use all the time..
Well, the values go up and down.. no matter what the time is.. I don't really think that's the case though. At first I thought it was the location of the file, or the file name, but that made no difference..
