NAME
pthread_exit —
terminate the calling
thread
LIBRARY
POSIX Threads Library (libpthread, -lpthread)
SYNOPSIS
#include <pthread.h>
void
pthread_exit(
void
*value_ptr);
DESCRIPTION
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.
RETURN VALUES
The
pthread_exit() function cannot return to its caller.
ERRORS
None.
