lgo_RpcGetHardwareId()

Retrieve the hardware identifier of a given driver on a particular server.

#include "laygo.h"

LResult lgo_RpcGetHardwareId
    (
        LServerId    serverId,
        LDriverId    driver
    );

lgo_RpcGetHardwareId() retrieves the hardware identifier of a given driver on a particular server. This enables an application to determine if a driver controls an intelligent board which requires downloading a driver module. This function should be called with a LDriverId parameter in the range 0 to N-1 where N is the number of drivers for which the stack is configured.

If successful, lgo_RpcGetHardwareId() returns the driver id. Otherwise, it returns a negative value indicating the reason it failed. Possible unsuccessful return values are:

• lgo_ERROR_DRIVER_NOT_INSTALLED

    lgo_RpcDisconnectServer(serverId);

    return (hwId);
}

    return (FAILURE);
