Redirected from: application binary interface

Definition: ABI


(Application Binary Interface) A specification for a specific hardware platform combined with the operating system. It is one step beyond the application program interface (API), which defines the calls from the application to the operating system. The ABI defines the API plus the machine language for a particular CPU family. An API does not ensure runtime compatibility, but an ABI does, because it defines the machine format. See API.
