gbp-stack-ffi

C ABI surface (cdylib + rlib) for the Group Protocol Stack.

This crate exposes a handle-based C ABI suitable for consumption from .NET (via P/Invoke) or any other FFI-capable runtime. The shared library is named gbp_stack (gbp_stack.dll on Windows, libgbp_stack.so / libgbp_stack.dylib on Unix).

gbp_last_error Thread-local last-error reporter
gbp_version Library version
gbp_mls_* RFC 9420 MLS context (handshake, exporter, AEAD)
gbp_node_* GBP-layer group node (framing, AEAD, replay, control)
gtp_client_* GTP (text) sub-protocol client
gap_client_* GAP (audio) sub-protocol client
gsp_client_* GSP (signalling) sub-protocol client
gbp_frame_* Frame codec helpers
gbp_error_* Error registry helpers

Memory protocol

  • Binary blobs are returned as GbpBuffer { ptr, len, cap } and MUST be released via gbp_buffer_free.
  • Owned strings are returned as *mut c_char and MUST be released via gbp_string_free.
