You can make the thread in detached state to avoid the memory leak if the thread should not be joined (or just expires on it's own).

To explicitly create a thread as joinable or detached, the attr argument in the pthread_create() routine is used. The typical 4 step process is:

• Declare a pthread attribute variable of the pthread_attr_t data type
• Initialize the attribute variable with pthread_attr_init()
• Set the attribute detached status with pthread_attr_setdetachstate()
• When done, free library resources used by the attribute with pthread_attr_destroy()
