I'm perhaps to dense to see this:
null_start(void *arg){
int i = (int ) arg;
while(!die[i]){
pthread_suspend_np(pthread_self());
if(thread_function[i]) thread_function[i](i);
thread_function[i] = 0;
}
return;
}
module_init:
pthread_t my_threads[NUMBER_OF_THREADS_WE_MIGHT_NEED];
for(i=0; i < NUMBER_OF_THREADS_WE_MIGHT_NEED; i++)
pthread_creat(&my_threads[i],null_start, ... );
/* can be called even from a RT interrupt */
activate_a_thread(i,f){
if(!thread_function[i])thread_function[i] = f;
pthread_kill(my_threads[i], RTL_SIG_WAKEUP);
}
...
add some synchronization and ...
Am I missing something?
