Log: Invoke the dirname() function in a POSIX compliant way. POSIX requires that the argument of dirname() is of type "char *". In other words, the input buffer can be modified by the function to store the directory name. Pull a copy of the string before calling dirname(). We don't care about freeing up the memory afterwards, as this is done at the very bottom of main(), right before the program terminates.
