[PATCH 0/4] Fix Unchecked return value Coverity errors

[Ryan Long]

Hi,

Here are some fixes for a few of the "Unchecked return value" Coverity
errors. Mainly, I just created a variable to store the status code returned 
from function calls and used the _Assert_Unused_variable_equals() macro
to assert that the call was successful. I also added a (void) in front
of the call to fsync() since that was getting flagged as well.

Thanks,
Ryan
