NAME

       pthread_exit() - cause the calling thread to terminate

SYNOPSIS

PARAMETERS

	      value_ptr The calling thread's exit status.

DESCRIPTION

       terminates the calling thread.  The calling thread returns an exit status in value_ptr.	This value is returned to a joining thread calling
       on the terminating thread.  Only threads created with the detachstate attribute value can return an exit status to The  exit  status  of  a
       detached thread is lost when the thread terminates.

       When a thread terminates, process-shared resources are not released.  Examples of process-shared resources include mutexes, condition vari-
       ables, semaphores, message queue descriptors, and file descriptors.  The routines are not called when a thread  terminates  as  this  is  a
       process termination action.

       An  implicit  call to is made when a thread returns from its start routine.  The function's return value serves as the thread's exit status
       (see pthread_create(3T)).  If the main thread returns from without calling the process will exit using the return value from  as  the  exit
       status.	 If  the  main	thread calls the process will continue executing until the last thread terminates or a thread calls After the last
       thread in the process terminates, the process will exit with an exit status of zero.

       Any installed cancellation cleanup handlers will be popped and executed in the reverse order that they were installed.  After the cancella-
       tion  cleanup handlers have been executed, if the thread has any non-NULL thread-specific data values with associated destructor functions,
       the destructor functions are called.  The order in which these destructor functions are called is unspecified.

       Calling from a cancellation cleanup handler or destructor function that was invoked because of  thread  termination  results  in  undefined
       behavior.

       After  a  thread  has terminated, the result of access to local (auto) variables of the thread is undefined.  The terminating thread should
       not use local variables for the value_ptr parameter value.

RETURN VALUE

       None.

ERRORS

       None, this function does not return.
