valgrind memory leak errors when using pthread_create

Question

I\'m writing a program using the pthread library. When I run my program with the command valgrind --leak-check=full, I get the following errors description:

Answer 1

A thread's resources are not immediately released at termination, unless the thread was created with the detach state attribute set to PTHREAD_CREATE_DETACHED, or if pthread_detach is called for its pthread_t.

An undetached thread will remain terminated state until its identifier is passed to pthread_join or pthread_detach.

To sum it up, you have three options:

1. create your thread with detached attribute set(PTHREAD_CREATE_DETACHED attribute)
2. Detach your thread after creation (by calling pthread_detach), or
3. Join with the terminated threads to recycle them (by calling pthread_join).

Hth.
