The function "perror" was called after a call of the function "fprintf"
in two if branches. So it could happen that an error message was displayed
for a failed print operation instead of the failure according to the call
of the function "fstat" or "open" here.

* Pass the relevant error data in the logging calls directly.

* Express that the corresponding return values are intentionally unused
  by casts to void.
