Windows CE includes socket options to access the unique features of the IrDA protocol, IRLMP_IAS_SET, IRMP_IRLPT_MODE, and IRLMP_EXCLUSIVE_MODE.
IRLMP_IAS_SET enables an application to set a single class in the local IAS. The application specifies the class to set, the attribute, and the attribute type. The application must allocate a buffer of the necessary size for the passed parameters. For more information on the using the IrDA protocols with Windows Sockets, see Creating an Infrared Winsock Application.
