Pthread_cond_wait

Hi,

I have a thread 'A' that tells other threads 'B' to start and then it waits for all other threads 'B' to finish.
static pthread_cond_t condStart = PTHREAD_COND_INITIALIZER;
static pthread_mutex_t mutexStart = PTHREAD_MUTEX_INITIALIZER;
static pthread_cond_t condFinish = PTHREAD_COND_INITIALIZER;
static pthread_mutex_t mutexFinish = PTHREAD_MUTEX_INITIALIZER;

in thread 'A'
pthread_cond_broadcast(&condStart,&mutexStart);

while(finishedCount<threadCount)
{
pthread_cond_wait(&condFinish,&mutexFinish);
finishedCount++;
}

in thread 'B'
pthread_cond_wait(&condStart,&mutexStart);
...do work....
pthread_cond_signal(&condFinish);


Sometimes, even though threads 'B' signal condFinish, thread 'A' does not recieve it...


Anyone knows whats going on?

Wel,, never used pthread meself so all I can start with is: are your variables finishedCount and threadCount properly initialized?
