That sounds like big system thinking.  Most of the time you don't need to
store a buffer full of input data to process it.  Eventually deep down
somewhere it will likely be processed a byte at a time.  You might as well
design your system to process the incoming data as a byte stream in the
first place.

Occasionally you may need to process a chunk of bytes together, like when
converting them from ASCII to integer, but that is still smaller than a
whole line or record or something.  Such small temporary buffers can often
be allocated by adding them to the stack since their use is local to the
current routine.
