In order to handle EINTR case for fclose (), we add a loop and check the return value of fclose (), however CodeCoverity
 tool flags a defect on it, please see attached screen shoot. Is EINTR ever set by fclose ()? If so, will it get set 
before or after file pointer is freed? 

I  checked an older version of fclose.c and didn't see that EINTR gets set, but I am not sure if the newer version 
changes that. We are using both 6.3.2 and 6.5 here.

Similarly, does EINTR set for fopen ()? Do we need to check it?

Thanks,
