Manually -> explicitly? The meaning of "manually" is "by hand and not by
machine". Software is always executed by a CPU (machine) so nothing

I see duplicated code in error paths. Please move the code for freeing
resources past the "return 0" statement and use goto statements to jump
to that code in case of an error.
Thanks,
