101 * @fn int sf_connect(sensor_type_t sensor)
102 * @brief This API connects a sensor type to respective sensor. The application calls with the type of the sensor (ex. ACCELEROMETER_SENSOR) and on basis of that server takes decision of which plug-in to be connected. Once sensor connected application can proceed for data processing. This API returns a positive handle which should be used by application to communicate on sensor type.

109 * @fn int sf_disconnect(int handle)
110 * @brief This API disconnects an attached sensor from an application. Application must use the handle retuned after attaching the sensor. After detaching, the corresponding handle will be released.

118 * @brief This API sends a start command to sensor server. This intimates server that the client side is ready to handle data and start processing. The parameter option should be '0' for current usages.
119 * @param[in] handle received handle value by sf_connect()
120 * @param[in] option With SENSOR_OPTION_DEFAULT, it stops to sense when LCD is off, and with SENSOR_OPTION_ALWAYS_ON, it continues to sense even when LCD is off

135 * @brief This API registers a user defined callback function with a connected sensor for a particular event. This callback function will be called when there is a change in the state of respective sensor. user_data will be the parameter used during the callback call. Callback interval can be adjusted using even_contion_t argument.

137 * @param[in] event_type your desired event_type to register it
138 * @param[in] event_condition input event_condition for special event. if you want to register without event_condition, just use a NULL value
139 * @param[in] cb your define callback function
140 * @param[in] user_data your option data that will be send when your define callback function called. if you don't have any option data, just use a NULL value
141 * @return if it succeed, it return zero value , otherwise negative value return

146 * @fn int sf_unregister_event(int handle, unsigned int event_type)
147 * @brief This API de-registers a user defined callback function with a sensor registered with the specified handle. After unsubscribe, no event will be sent to the application.
148 * @param[in] handle received handle value by sf_connect()
149 * @param[in] event_type your desired event_type that you want to unregister event
