dbuffer (short for "disk buffer") is a threaded buffering program for data
streams on disk. Its interface is modeled after the program called buffer, but
while buffer creates a buffer solely in memory, dbuffer builds only small input
and output buffers in memory and can put huge amounts of data on disk. This
method vastly increases the possible size of a buffer. dbuffer can be useful
for buffering slow network transfers for later continous fast processing. It
can also be used for creating data to be stored temporarily on disk without
growing beyond a certain limit to ensure a minimum transfer rate, which is
necessary for several applications, including CD-ROM recording.
