   5 NAME
   6        lf64 - transitional interfaces for 64-bit file offsets
   7 
   8 DESCRIPTION
   9        The data types, interfaces, and macros described on this page provide
  10        explicit access to 64-bit file offsets. They are accessible through the
  11        transitional compilation environment described on the lfcompile64(5)
  12        manual page. The function prototype and semantics of a transitional
  13        interface are equivalent to those of the standard version of the call,
  14        except that relevant data types are 64-bit entities.
  15 
  16    Data Types
  17        The following tables list the standard data or struct types in the
  18        left-hand column and their  corresponding explicit 64-bit file offset
  19        types in the right-hand column, grouped by header. The absence of an
  20        entry in the  left-hand column indicates that there is no existing
  21        explicit 32-bit type that corresponds to the 64-bit type listed in the
  22        right--hand column.  Note that in a 64-bit application, the standard
  23        definition is equivalent to the 64-bit file offset definition.

 109    System Interfaces
 110        The following tables display the standard API and the corresponding
 111        transitional  interfaces for 64-bit file offsets. The interfaces are
 112        grouped by header. The interface name and the affected data types are
 113        displayed in courier font.
