c - Can't stop reading Unicode file with !feof()

itemprop="text">

I don't know why while loop can't
stop. It can't compare c with Delim neither stop by reaching
eof.

wchar_t* Getline(const
            wchar_t* Filename, const wchar_t Delim){


FILE* f =
            _wfopen(Filename, L"r, ccs=UTF-8");

wchar_t* info =
            NULL;
wchar_t* temp = NULL;
int count = 1;
int i =
            0;
wchar_t c;

c =
            fgetwc(f);


while (c != Delim ||
            !feof(f))
{
 count++;
 temp = (wchar_t*)realloc(info,
            count * sizeof(wchar_t));

 if (temp)
 {
 info =
            temp;
 info[i] = c;
 i++;


            }

 else
 {
 free(info);

            wprintf(L"Failed to read\n");
 }
 c =
            fgetwc(f);
}
info[i] =
            '\0';


fclose(f);
return
            info;

}

After
reading all character in file. It seem not to stop. Even c are the same with Delim. And
!feof(f) hasn't worked too. I have try c != WEOF but fail
too

I thought that the problem is in the file
that I read but not. I have change another file but the same
problem.

Thanks for helping me!

Answer

You wish to loop whilst you have not got a
Delim character and it is not the end of the file, so
replace the || with
&&

while
            (!feof(f) && c !=
            Delim)

Edit:
the order has also been changed in response to comments
