Function mynewt::hw::sensor::sensor_mgr_find_next

pub unsafe extern "C" fn sensor_mgr_find_next(
    arg1: sensor_mgr_compare_func_t, 
    arg2: *mut c_void, 
    arg3: *mut sensor
) -> *mut sensor

The sensor manager contains a list of sensors, this function returns the next sensor in that list, for which compare_func() returns successful (one). If prev_cursor is provided, the function starts at that point in the sensor list.

@warn This function MUST be locked by sensor_mgr_lock/unlock() if the goal is to iterate through sensors (as opposed to just finding one.) As the "prev_cursor" may be resorted in the sensor list, in between calls.

• compare_func: The comparison function to use against sensors in the list.
• arg: The argument to provide to that comparison function
• prev_cursor: The previous sensor in the sensor manager list, in case of iteration. If desire is to find first matching sensor, provide a NULL value.

Return: A pointer to the first sensor found from prev_cursor, or NULL, if none found.
