the developer list is very busy...

I'm successfully using mmap but now wish to improve my understanding...

in particular how to get the values of a frame in the buffer?

write(STDOUT_FILENO, buffers[buf.index].start, Buffersize); sends one 
frame from the buffer to stdout

what would be the syntax to iterate through that frame of the buffer?
ie to get each of the 0-255 values for a frame

regards
