I'm build multi-processes communication program.
Example i have two processes : Client and Server. At Client side, i pass [DataType] to Server, example: [StringT, IntT, CharT] Server will handle "user input" with [DataType] and return result [String] to Client side, example: ["string", "001", "c"] Then at Client side, i need parse [String] to get real value: ("string", 001, 'c') Because, [DataType] have many different case, so i want pass [String] between processes, and use TH parse result [String] at Client side.
