race condition on STL vector

hi,

I would like to know if this is a race condition on the STL vector class. The code is below.

class Buffers {
 public:
  Buffers() : sig_buff(NUM_BUFFERS) { }
  ~Buffers(){ }
  vector<buff>::iterator operator[](int dex) 
  {
    vector<buff>::iterator it = (pthread_mutex_lock(&sig_buff[dex].mutex)?it:sig_buff.begin()+dex); 
    return it;
  }
  void release_buffer(int dex) 
  { 
   pthread_mutex_unlock(&sig_buff[dex].mutex);
  }
 private:
  vector<buff> sig_buff;
};


Thanks,
Jim Smith
