There exist a few filters that help tapes streams by buffering IO and
|
|
allowing reads to overlaps with writes under Unix. Most of these filters
|
|
rely on relatively unportable features, for example SYSV like shared
|
|
memory.
|
|
|
|
team is a filter that runs essentially unchanged on any Unix version, as
|
|
it relies only on features present in V7. A number of team processes
|
|
(team members) share a common input fd and a common output fd, and they
|
|
take turns at reading from the former and writing to the latter; they
|
|
synchronize by using a ring of pipes between them, where a "read-enable"
|
|
and a "write-enable" token circulate.
