yarp::os::idl::WireReader reader; // initialize WireReader if (!reader.read(port)) { // read from port reader.fail(); // indicate failure return; // exit function }
yarp::os::idl::WireReader reader; // initialize WireReader bool success = reader.read(data, size); // read data from message if (!success) { // check for failure reader.fail(); // indicate failure }This example uses the `read` method to read a specific amount of data from a message. The `fail` method is used to indicate failure if the data cannot be read successfully. The `yarp.os.idl` library is part of the YARP (Yet Another Robot Platform) robotics library, which provides tools and libraries for robotics research and development.
