Message "Nothing from keyboard!" and exit GTK Application.

["정진영" <jpjude nate com>]

Hello everyone,
I am currently coding a program that GTK Application using thread on linux-fb(linux frame buffer).
It working good except title Message "Nothing from keyboard!".

After starting GTK Application, It's good working for a moment.
But, after a moment when no touch keyboard,
the GTK Application is exit with the message "Nothing from keyboard!".

How can I solve this problem?
For your understand, including code below.

Thanks,
Jinyo

static void key_loop() {
    int count=0;
    long lbuff=0;
   
    echo_disable();
    while (lbuff != CPGUI_KEY_ESC) {
        lbuff = 0;
        read(0, &lbuff, 3);
       
        switch (lbuff) {
        case CPGUI_KEY_ARROW_UP : 

            break;
        case CPGUI_KEY_F3 :
            printf("key: f3~");
            cpmenu_show_setup();
            break;
        case CPGUI_KEY_ESC :
           
            break;
        }
        //printf("key: %d \n", lbuff);
