interface64(5)

NAME

interface64 − 64-bit transitional interfaces

DESCRIPTION

The interfaces, macros, and data types described on this page section are explicit 64-bit instances of the standard API. 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 table shows the standard data or struct types and their corresponding 64-bit types. The absence of an entry in the Standard Definition column indicates that there is no existing 32-bit type that corresponds to the type listed in the 64-bit Definition column.
