NAME
lf64 - transitional interfaces for 64-bit file offsets
DESCRIPTION
The data types, interfaces, and macros described on this
page provide explicit access to 64-bit file offsets. They
are accessible through the transitional compilation environ-
ment described on the lfcompile64(5) manual page. The func-
tion prototype and semantics of a transitional interface are
equivalent to those of the standard version of the call,
except that relevant data types are 64-bit entities.
Data Types
The following tables list the standard data or struct types
in the left-hand column and their corresponding explicit
64-bit file offset types in the right-hand column, grouped
by header. The absence of an entry in the left-hand column
indicates that there is no existing explicit 32-bit type
that corresponds to the 64-bit type listed in the right-hand
column. Note that in a 64-bit application, the standard
definition is equivalent to the 64-bit file offset defini-
tion.

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