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.
