Hi!

As far as I can see this code tests that read() has returned negative
value and in this case errno must be set.
I.e.
if ret >= 0 -> read hasn't failed -> FAILURE
The errno != errnum is not evaluated unless the first condition has
failed (that means ret < 0) and in this case errno must be set.
The condition is equivalent to !(ret < 0 && errno == errnum)
Or am I missing something?
