io library
dart:io-only additions for mcp_io_scpi.
Importing the main library keeps the package web-safe (ScpiAdapter
InMemoryScpiTransportonly). Importing thisiolibrary opts in to TCP-based instrument transports — VXI-11 RPC today, raw TCP/Telnet additions land here in future phases.

Functions
-
decodeReply(
List< int> body) → OncRpcReply - Decode an ONC RPC reply message body (without the record marker).
-
encodeCall(
{required int xid, required int program, required int version, required int procedure, required List< int> args}) → Uint8List - Build a complete ONC RPC CALL message (no record marker — caller wraps via wrapRecord).
-
parseRecord(
Uint8List bytes) → OncRpcRecord? -
Parse a single ONC RPC record from the head of
bytes. Returnsnullwhen fewer than 4 header bytes have arrived, or when the declared payload length exceeds what's buffered. -
wrapRecord(
List< int> body) → Uint8List - Wrap an RPC message body in an ONC RPC record marker (RFC 1057 §10) — last-fragment + length in a 4-byte big-endian header.
