@section Atomicity of Pipe I/O

|

Reading or writing pipe data is @dfn{atomic} if the size of data written
|
||||
is less than @code{PIPE_BUF}. This means that the data transfer seems
|

to be an instantaneous unit, in that nothing else in the system can

observe a state in which it is partially complete. Atomic I/O may not
