Vapi
Noun · Development
Definitions
A Vala API file (.vapi) that provides bindings to C libraries for the Vala programming language. Vapi files describe C function signatures, types, and GObject classes so Vala can call them with type safety.
In plain English: A file that tells the Vala language how to talk to a C library, translating C functions into something Vala understands.
Example: "Write a .vapi file for the C library so we can call it from Vala with proper type checking."
