pthread_exit - thread termination
void pthread_exit(void *value_ptr);
The pthread_exit() function terminates the calling thread and makes the value value_ptr
available to any successful join with the terminating thread. 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, appropriate 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
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 behaviour 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
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
pthread_exit() value_ptr parameter value.
The process exits with an exit status of 0 after the last thread has been terminated. The
behaviour is as if the implementation called exit() with a zero argument at thread termination
The pthread_exit() function cannot return to its caller.
No errors are defined.
The pthread_exit() function will not return an error code of [EINTR].
