NAME

       writebuffer - write output to devices which don't like constant stopping and starting

SYNOPSIS

       writebuffer [--mlock] [size]

DESCRIPTION

       writebuffer reads data on standard input and writes it to standard output.  It will buffer
       internally up to size megabytes and will only write data when the buffer is at  least  75%
       full or when there is no more input to fill the buffer.

       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  writes  are  undesirable  for
       performance reasons, e.g. tape drives.

OPTIONS

       --mlock
              Calls mlock(2) to lock the buffer into memory.
