-.Dt PTHREAD_EXIT 3
-.Os
-.Sh NAME
-.Nm pthread_exit
-.Nd terminate the calling thread
-.Sh SYNOPSIS
-.Fd #include <pthread.h>
-.Ft void
-.Fn pthread_exit "void *value_ptr"
-.Sh DESCRIPTION
-The
-.Fn pthread_exit
-function terminates the calling thread and makes the value
-.Fa value_ptr
-available to any successful join with the terminating thread.
-Any
-cancellation cleanup handlers that have been pushed and are not yet popped
-are popped in the reverse order that they were pushed and then executed.
-After all cancellation handlers have been executed, if the thread has any
-thread-specific data, appropriate destructor functions are 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
-.Fn atexit
-routines that may exist.
-.Pp
-An implicit call to
-.Fn pthread_exit
-is made when a thread other than the thread in which
-.Fn 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.
-.Pp
-The behavior of
-.Fn pthread_exit
-is undefined if called from a cancellation handler or destructor function
-that was invoked as the result of an implicit or explicit call to
-.Fn pthread_exit .
-.Pp
-After a thread has terminated, the result of access to local (auto)
-variables of the thread is undefined.
-Thus, references to local variables
-of the exiting thread should not be used for the
-.Fn pthread_exit
-.Fa value_ptr
-parameter value.
-.Pp
-The process will exit with an exit status of 0 after the last thread has
-been terminated.
-The behavior is as if the implementation called
-.Fn exit
-with a zero argument at thread termination time.
-.Sh RETURN VALUES
-The
-.Fn pthread_exit
-function cannot return to its caller.
-.Sh ERRORS
-None.
-.Sh SEE ALSO
-.Xr _exit 2 ,
-.Xr exit 3 ,
-.Xr pthread_create 3 ,
-.Xr pthread_join 3
-.Sh STANDARDS
-.Fn pthread_exit
-conforms to
