I have one dynamic library(dylib) and one application(app). Actually I am porting something from Windows so I will write about windows code. In Application, I create one event object (eventName). Now, I create one thread and call waitForSingleObject and now it is waiting for someone to set the event and the it will come out. In DLL I create one event object of same name (eventName). Now, whenever I need, set the event in DLL then in application that thread comes out of wait and executes the code and again start waiting. You are describing a condition variable, which is a simplified case of a counting semaphore. Google either of these. -- Terry This email sent to site_archiver@lists.apple.com
