I have 2 tasks in which Task A should wait until Task B exits(both tasks have respective functionalities). In linux this can be be achieved by pthreadjoin(). Is it possible to implement the pthreadjoin() functioniality in freertos..?
there is no equivalent although you could code your own using easily enough if the task being deleted knows it has to notify another task. That could be done by manually calling a sync primitive or perhaps with a trace macro.
Its rare for threads to get deleted in FreeRTOS applications. Perhaps if you describe the scenario sombody could suggest and alternative approach.
