Sorry something is not clear for me.
what does this mean

int i;
i = 0;

I defined a variable and used it.

If fullpath_length is not really used, I should not receive any error by commenting that. Like this:
   

int length/*, fullpath_length*/;

But I get this error

syscall.c:1023:3: error: ‘fullpath_length’ undeclared (first use in this function)


the line it points is
fullpath_length = strlen(fullpath);


// Naderan *Mahmood;

No, it's not.  It's a set of fullpath_length.
