All of the functions (as far as I can tell) are listed there as well as descriptions for each function.

Thank You for the link. It was certainly helpful but I still quite confuse with this function:
========
int alt_video_display_buffer_is_available(alt_video_display* display);
This function returns the next free frame buffer available for display. The
function returns a condition code of 0 if an empty buffer is found; any
other return value indicates failure. The function accepts the following
parameter:
■ display: This variable is a pointer to a data structure that keeps
track of all of the frame buffer information, including the start
addresses for all of the frame buffers.
========
It says that it return 0 or other number indicates failure. Then, my question is, where is the frame I want goes? I need the frame to do analysis before display. Thank you.
