Does anybody have ideas about how to implement a simple circular 
buffer?  I'm not sure if I am using the term circular buffer correctly 
so I'll try and explain what I'm looking for. 
 
For example if the buffer were only five bytes long, and the data 
'Hello World' was put into the buffer it would appear to move like 
this... 
 
byte 0-> . . . . . <- byte 5        ; Init 
byte 0-> . . . . H <- byte 5        ; 1 
byte 0-> . . . H e <- byte 5        ; 2  
byte 0-> . . H e l <- byte 5        ; 3 
byte 0-> . H e l l <- byte 5        ; 4  
byte 0-> H e l l o <- byte 5        ; 5 
byte 0-> e l l o   <- byte 5        ; 6 
byte 0-> l l o   W <- byte 5        ; 7 
 
New data would always enter the buffer at the bottom, pushing old data 
up.  Any data that could not fit in the buffer would fall off the top. 
 
Any help will be greatly appreciated.  Thanks
