Hi guys, this is my first post. I'm a guy and I like programming C. I study at university and I hope to find here friendly people :)

Now I've got this problem.

I've constructed a struct like this:

struct alfa
{
uint32_t beta1;
uint32_t beta2;
};
struct alfa gamma;
Then I need to move cursor with an fseek(), so:

fseek(file,gamma.beta1,SEEK_CUR);

the result is wrong...but why?!

gamma.beta1 is not like a normal int?! how can I do to move cursor about beta1 value?

Ok...by "cursor" do you mean the cursor on the screen? You can't do that by fseek'ing. Otherwise I have no idea what you meant.

@Dargueta, Probably an accidental reference to something from another language, he means position.

Where did you initialize gamma.beta1 in your script? How is the result "wrong"?, you left out a lot of information.

@Nullw0rm: I've seen this problem before, so I had to ask.
@stefanostefano: You have to set gamma.beta1 to some reasonable value before using it in fseek(). Otherwise, who knows what bizarre value it'll hold. Could be -234874 for all we know.
