pthread_exit(3)pthread_exit(3)NAMEpthread_exit - Terminates the calling thread
SYNOPSIS
#include <pthread.h>
void pthread_exit(
void *value_ptr );
LIBRARY
DECthreads POSIX 1003.1c Library (libpthread.so)
STANDARDS
Interfaces documented on this reference page conform to industry stan‐
dards as follows:
IEEE Std 1003.1c-1995, POSIX System Application Program Interface
PARAMETERS
Value copied and returned to the caller of pthread_join(3). Note that
void * is used as a universal datatype, not as a pointer. DECthreads
treats the value_ptr as a value and stores it to be returned by
pthread_join(3).
DESCRIPTION
This routine terminates the calling thread and makes a status value
(value_ptr) available to any thread that calls pthread_join(3) and
specifies the terminating thread.
Any cleanup handlers that have been pushed and not yet popped from the
stack, are popped in the reverse order that they were pushed and then
executed. After all cleanup handlers have been executed, appropriate
destructor functions shall be called in an unspecified order if the
thread has any thread-specific data. 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 routine that may exist.
An implicit call to pthread_exit(3) is issued when a thread returns
from the start routine that was used to create it. DECthreads writes
the function's return value as the return value in the thread's thread
object. The process exits when the last running thread calls
pthread_exit(3).
After a thread has terminated, the result of access to local (that is,
explicitly or implicitly declared auto) variables of the thread is
undefined. So, references to local variables of the existing thread
should not be used for the value_ptr argument of the pthread_exit(3)
routine.
