// \chapter{Supporting threads made outside of GUSI}
|
|
//
|
|
// As convenient as the pthreads interface is, some applications may link to other
|
|
// libraries which create thread manager threads directly, such as the PowerPlant
|
|
// thread classes.
|
|
//
|
|
// Unfortunately, there is no really elegant way to welcome these lost sheep into the
|
|
// pthread flock, since the thread manager offers no way to retrieve thread switching
|
|
// and termination procedures. We therefore have to resort to a violent technique used
|
|
// already successfully for MPW support: On CFM, we override the default entry point and
|
|
// use the CFM manager to find the real implementation.
|
|
//
|
|
// For non-CFM, we unfortunately don't have such an effective technique, since the
|
|
// thread manager is called through traps (and no, I'm not going to patch any traps
|
|
// for this). You will therefore have to recompile your foreign libraries with
|
|
// a precompiled header that includes \texttt{GUSIForeignThreads.h}.
|
|
//
|
|
// <GUSIForeignThreads.h>=
