/* The <sys/types.h> header contains important data type definitions.
 * It is considered good programming practice to use these definitions, 
 * instead of the underlying base type.  By convention, all type names end 
 * with _t.
 */

/*  N.B Not all these types are relevant within QDOS, but they are left
 *      in for guidance in case any routines are ported to QDOS.
 */

/* The type size_t holds the result of the size_of operator.  At first glance,
 * it seems obvious that it should be an unsigned int, but this is not always 
 * the case. For example, MINIX-ST (68000) has 32-bit pointers and 16-bit
 * integers. When one asks for the size of a 70K struct or array, the result 
 * requires 17 bits to express, so size_t must be a long type.
