No, but I have seen cases where errno won't be reset on success (errno !=
0 and file != NULL).  I'd just rather test for the real error, then check
errno.

Basically, fopen()'s return values are defined as follows:

       Upon  successful  completion  fopen,  fdopen  and  freopen
       return  a  FILE  pointer.  Otherwise, NULL is returned and
       the global variable errno is set to indicate the error.

So, errno isn't defined if fopen() returns a good pointer.
