 Higher level basic types

 OSErr                   16-bit result error code
 OSStatus                32-bit result error code
 LogicalAddress          Address in the clients virtual address space
 ConstLogicalAddress     Address in the clients virtual address space that will only be read
 PhysicalAddress         Real address as used on the hardware bus
 BytePtr                 Pointer to an array of bytes
 ByteCount               The size of an array of bytes
 ByteOffset              An offset into an array of bytes
 ItemCount               32-bit iteration count
 OptionBits              Standard 32-bit set of bit flags
 PBVersion               ?
 Duration                32-bit millisecond timer for drivers
 AbsoluteTime            64-bit clock
 ScriptCode              A particular set of written characters (e.g. Roman vs Cyrillic) and their encoding
 LangCode                A particular language (e.g. English), as represented using a particular ScriptCode
 RegionCode              Designates a language as used in a particular region (e.g. British vs American
 English) together with other region-dependent characteristics (e.g. date format)
 FourCharCode            A 32-bit value made by packing four 1 byte characters together
 OSType                  A FourCharCode used in the OS and file system (e.g. creator)
 ResType                 A FourCharCode used to tag resources (e.g. 'DLOG')
