pthread_join function

Hi,
I would like to know if the call
of pthread_join( thread,&status) for a thread already created
in main function will free the memory allocated to thread after the pthread_join retruns or should I wait the
termination of main function?
Is there any need to cancel or exit the thread if I don't want to wait
the end of main function?
Note : status is void *status.

Thanks,
Regrads

pthread_detach(3C)					   Standard C Library Functions 					pthread_detach(3C)

NAME
pthread_detach - detach a thread SYNOPSIS
cc -mt [ flag... ] file... -lpthread [ library... ] #include <pthread.h> int pthread_detach(pthread_t thread); DESCRIPTION
The pthread_detach() function is used to indicate to the implementation that storage for the thread thread can be reclaimed when that thread terminates. In other words, pthread_detach() dynamically resets the detachstate attribute of the thread to PTHREAD_CRE- ATE_DETACHED. After a successful call to this function, it would not be necessary to reclaim the thread using pthread_join(). See pthread_join(3C). If thread has not terminated, pthread_detach() will not cause it to terminate. The effect of multiple pthread_detach() calls on the same target thread is unspecified. RETURN VALUES
If successful, pthread_detach() returns 0. Otherwise, an error number is returned to indicate the error. ERRORS
The pthread_detach() function will fail if: EINVAL The implementation has detected that the value specified by thread does not refer to a joinable thread. ESRCH No thread could be found corresponding to that specified by the given thread ID. ATTRIBUTES
