SOL_IRLMP Socket Options

  • Article

The following table describes SOL_IRLMP socket options that apply to sockets created for the Infrared Data Association (IrDA) address family (AF_IRDA) and the InfraRed Link Management Protocol (IRLMP). See the getsockopt and setsockopt function reference pages for more information on getting and setting socket options.

To enumerate protocols and discover supported properties for each installed protocol, use the WSAEnumProtocols, WSCEnumProtocols, or WSCEnumProtocols32 function.
