        Just like QtAssiant, it's deserved to collection an user guide while learning GuiLite, so I prepare to follow the source code folder tree strcution to make an Assiant, and then name it GtAssiant.

        c_audio class: Create a thread and monitor variant, while the variant equal critical condition, play sound 'heart_beat.wav' . It's thread safe.

                {
                    AUDIO_HEART_BEAT,
                    AUDIO_ALARM,
                    AUDIO_MAX
                };    

static int play(AUDIO_TYPE type)

    int read_usr_msg(MSG_INFO* msg);

c_fifo class	It's a circule link list, use to save unsigned char buffer.It's thread safe.
c_fifo(const char* name)
int read(void* buf, int len)	Read specific length data from buffer
int write(void* buf, int len)	Write specific length data into buffer, maximum save length is 1024

c_hid_pipe class	It's a circule link list, use to save unsigned char buffer.It's thread safe.
static int read_hid_msg()	Read msg from memory by c_fifo class
static int write_hid_msg(MSG_INFO* msg, unsigned int display_id = 0)	Write msg into memory by c_fifo class
