Some more feedback:
* Use a more sensible formatting style (look at the suckless.org
projects or style(9) in OpenBSD.)
* If a function is not intended to accept any arguments use void.
Instead of:
void foo();
Use:
void foo(void);
* Use BUFSIZ wherever possible instead of hardcoded values.
* Consider using the functions from err.h instead of the
fprintf() + strerror() + exit() combination. As an alternative, you
can grab the eprintf() + friends from sbase.
* No need to include the type of the variable in the name, so things
like "statistics_string" look weird.
* Use strtonum() or estrtol() from sbase instead of atoi().
* Errors should to go to stderr.
* Don't use EXIT_{SUCCESS,FAILURE} - just use 0 and 1. I know this
is debatable but saves typing and verbosity.
* Fix your indentation!
