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 environment described on the lfcompile64(5) manual page. The function 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 definition.
