Nios UP vga

[Altera_Forum]

Hi all , 

 Where can i read details about functions like :  alt_up_pixel_buffer_open_dev(); and alt_up_pixel_buffer_draw(); etc all that relate to vga SOC in UP .  I have read Altera ip Cores for DE boards , but it does not any details or examples of how to use these functions e.g    CHAR_BUFFER= alt_up_char_buffer_open_dev("/dev/video_character_buffer_with_dma_0");  where can i find /dev/video_character_buffer_with_dma_0 , i dont see any dev folder in my project ????  Regards ,
