Syscall Node

The Syscall Node performs function call operations within the system. This node processes system calls based on the opcode, passing input packets to the function for execution and returning the result.

Specification

• opcode: A string identifying the system operation to be invoked. It is associated with the specified function and determines the node's behavior.

Ports

• in: Receives input packets and converts them into arguments for the specified function call. The payload of the packet is adjusted to match the function's parameters.
• out: Returns the result of the function call. If the function returns multiple values, the result is output as an array.
• error: Returns any errors encountered during the function call.

Example

- kind: snippet
  language: cel
  code: 'has(self.body) ? self.body : null'
  ports:
    out:
      - name: specs_create
        port: in

- kind: syscall
  name: specs_create
  opcode: specs.create
