Why this is an endless loop?

Simple:

I want to get the size of a file but the following code loops forever and freezes my application:

Code:

---

FILE *file;
int filesize;

while(!feof(file))
        {
                       
              filesize++;
        }

---

What is wrong with this code and why does it freeze?

Because you arent doing anything to the file. You are basically doing this:

Code:

---

for(INT fileSize = 0; ; ++fileSize);

---

There is no condition to end the loop, because you arent seeking the file.

So how can I get the file size using C functions - not API

Very likely, there is a function that will retrieve a files attributes. Look around in the MSDN.

Grrrr... =).

heheh :p

How come MSDN has the resource for general C\C++ programming language

It doesn't have the resource, it's just a resource available. It just happens to be a very useful resource though, especially if you're using Windows.

You'll need to actually open a file before you can get its attributes, currently you're just declaring a pointer to a file. The standard C way to do that is using fopen().

You can also use _stat to get the file's information. Search for stat.c and that will give an example :)

Sorry, I just wrote the code in post. I had already opened the file using "fopen" command;)

try something like GetFileAttributes{API though}
