2000-04-28 Sebastian Wilhelmi <wilhelmi@ira.uka.de> * gasyncqueue.c: New File implementing an asynchronous queue to be used for asynchronous inter-thread communication. * gthreadpool.c: New File implementing a thread pool to be used for distributing work among several threads. * glib.h: Added the type and function declarations for these two types. * tests/threadpool-test.c: New File implementing a test for the thread pool. This also checks the asynchronous queue underlying the thread pool. * tests/Makefile.am: Changed accordingly.
