pthread_exit - terminate the calling thread
#include <pthread.h>
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 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
atexit() routines
that may exist.
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
handler or destructor function that was invoked as the result of 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
variables of
the exiting thread should not be used for the pthread_exit()
value_ptr
parameter value.
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 exit()
with a zero argument at thread termination time.
The pthread_exit() function cannot return to its caller.
None.
_exit(2), exit(3), pthread_create(3), pthread_join(3)
pthread_exit() conforms to ISO/IEC 9945-1:1996 (``POSIX'').
