Re: variable âsomethingâ set but not used [-Wunused-but-set-variable]

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:
ÂÂ
int length/*, fullpath_length*/;
But I get this error
syscall.c:1023:3: error: âfullpath_lengthâ undeclared (first use in this function)
the line it points is
fullpath_length = strlen(fullpath);

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