     NAME
          types - primitive system data types

     SYNOPSIS
          #include <sys/types.h>

     DESCRIPTION
          The data types defined in the include file are used in
          A/UX(Reg.) system code; some data of these types are acces-
          sible to user code:

                 * System-dependent parameters and types
               */

          The form daddr_t is used for disk addresses except in an
          inode on disk (see fs(4)).  Times are encoded in seconds
          since 00:00:00 GMT, January 1, 1970.  The major and minor
          parts of a device code specify kind and unit number of a
          device and are installation-dependent.  Offsets are measured
          in bytes from the beginning of a file.  The label_t vari-
          ables are used to save the processor state while another
          process is running.
