Open a named pipe having the specified `pipeName`, and start a thread to read messages and dispatch them to the callback specified at construction. Optionally specify `attributes` of the background processing thread. If `attributes` is not supplied, a default constructed `ThreadAttributes` object will be used. Return 0 on success, and a non‐zero value otherwise. In particular, return a non‐zero value if the pipe cannot be opened or if it is detected that another process is reading from the pipe. `pipeName` must be of the types `const char *`, `char *`, `bsl::string`, `std::string`, `std::pmr::string` (if supported), or `bslstl::StringRef`.
