There was similar question on stackoverflow already: WaitForSingleObject and WaitForMultipleObjects equivalent in linux

In addition you can use semaphores:

sem_t semOne  ;
sem_t semTwo  ;
sem_t semMain ;

In main thread:

sem_init(semOne,0,0) ;
sem_init(semTwo,0,0) ;
sem_init(semMain,0,0) ;

...


sem_wait(&semMain);

// Thread 1
sem_wait(&semOne);
sem_post(&semMain);


// Thread 2
sem_wait(&semTwo);
sem_post(&semMain);
