Sys

Raw FFI bindings for libdave - the C interface to Discord’s DAVE end-to-end encryption protocol.

This module loads libdave via stdPolyfills.ffi.dlopen and exposes the full C API as a typed Luau interface. It is a low-level binding layer; higher-level wrappers should be built on top of lib rather than consuming this module directly.
