NAME
readbuffer - read input from devices which don’t like constant stopping
and starting
SYNOPSIS
readbuffer [--mlock] [size]
DESCRIPTION
readbuffer reads data on standard input and writes it to standard
output. It will internally buffer up to size megabytes of data, and
will only read more data when the buffer is at least 75% empty.
size may also be suffixed with m, k, or b to indicate that it is in
megabytes (2^20), kilobytes (2^10) or bytes.
It is intended for use in situations where many small reads are
undesirable for performance reasons, e.g. tape drives.
OPTIONS
--mlock
Calls mlock(2) to lock the buffer into memory.
