Foil 10 Multithreading on Unix-compliant Operating Systems -- 3: DCE Threads

From Master Foils for Threads with TCE in detail CPS600 Spring Semester95 -- April 1995. by Janusz Niemiec and Geoffrey Fox * See also color IMAGE
The most complete, and at the same time complex, thread package has been furnished by the Open Software Foundation (OSF); the Distributed Computing Environment(DCE) threads package. It contains 51 primitives, some of them not strictly necessary but provided for convenience only.
  • This thread model can be implemented as kernel- or user-level threads. Its scheduling can be preemptive, non-preemptive, prioritized, round-robin or even other algorithms can be specified. The user has the choice to select one of them.
There are calls for a thread creation, destruction, killing and exiting. A newly created thread becomes a child of the thread which created it. The parent can either wait for child's death (join operator) or it may forget that a child exist -- detaching it from its execution (detach operator).
