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.

NAME

       pthread_exit - terminate calling thread

SYNOPSIS

       cc -mt [ flag... ] file... -lpthread [ library... ]
       #include <pthread.h>

       void pthread_exit(void *value_ptr);

DESCRIPTION

       The  pthread_exit() function terminates the calling thread, in a similar way that exit(3C) terminates the calling process. If the thread is
       not detached, the exit status specified by  value_ptr is  made	available  to  any  successful	join  with  the  terminating  thread.  See
       pthread_join(3C). Any cancellation cleanup handlers that have been pushed and not yet popped are popped in the reverse order that they were
       pushed and then executed. After all cancellation cleanup handlers have been executed, if the thread has any thread-specific data, appropri-
       ate  destructor	functions  will  be  called  in  an unspecified order. Thread termination does not release any application visible process
       resources, including, but not limited to, mutexes and file descriptors, nor does it perform any process level cleanup  actions,	including,
       but not limited to, calling any atexit() routines that might exist.

       An  exiting thread runs with all signals blocked. All thread termination functions, including cancellation cleanup handlers and thread-spe-
       cific data destructor functions, are called with all signals blocked.

       An implicit call to pthread_exit() is made when a thread other than the thread in which main() was first invoked  returns  from	the  start
       routine that was used to create it. The function's return value serves as the thread's exit status.

       The  behavior  of  pthread_exit()  is  undefined if called from a cancellation cleanup handler or destructor function that was invoked as a
       result of either an implicit or explicit call to pthread_exit().

       After a thread has terminated, the result of access to local (auto) variables of the thread is undefined. Thus, references to  local  vari-
       ables of the exiting thread should not be used for the pthread_exit() value_ptr parameter value.

       The  process  exits  with  an  exit status of  0 after the last thread has been terminated. The behavior is as if the implementation called
       exit() with a 0 argument at thread termination time.

RETURN VALUES

       The pthread_exit() function cannot return to its caller.

ERRORS

       No errors are defined.
