 Notes on usage:
 * IO_SIZE_BITS specifies the number of bits used for file-I/O-related operations. In particular, the size of return values for Read/Write functions in dependent libraries are based on it
-* If IO_SIZE_BITS is the same size as size_t, the Read/Write functions in dependent libraries do not work properly if the MSB of a size_t variable specifying the size to be read/Written is used. For example, if IO_SIZE_BITS is 32 and sizeof(size_t) is 4, the maximum size (parameter value) that the Read/Write function can work with is 2^31 - 1, i.e., the 32nd bit cannot be used. If it is used, the return value of the functions will be intereted as an error (since it is interpreted as a negative number)
-* Error codes have to be negative in order to distinguish them from return values which signal the amount of bytes read/written (which is positive)
