81 * @param[in] name name of the parameter
82 * @param[in] type type of the parameter
84 * @note These provide the config data defined by the userland
85 * for this device. It can be queried at any time, given the name string
86 * Only two types are supported
87 * ADF_OS_PARAM_TYPE_STRING
88 * ADF_OS_PARAM_TYPE_INT32
89 * For example, say, the parameters name "my_int" and "my_name" are of
90 * variables of type int and string respectively. Then you would declare them
93 * adf_os_declare_param(my_int, ADF_OS_PARAM_TYPE_INT32);
94 * adf_os_declare_param(my_name, ADF_OS_PARAM_TYPE_STRING);
96 * To read the userland provided config value, you would do something like
99 * adf_os_read_param(my_name, &softc->sc_my_name);
104 * st = adf_os_read_param(my_int, &softc->sc_my_int);
