pthread_exit(3c)
Standard C Library Functions pthread_exit(3C)
NAME
pthread_exit - terminate calling thread
SYNOPSIS
#include <pthread.h>
void pthread_exit(void *value_ptr);
DESCRIPTION
The pthread_exit() function terminates the calling thread, in a similar
way that exit(3C) terminates the calling process. If the thread is not
detached, the exit status specified by value_ptr is made available to
any successful join with the terminating thread. See pthread_join(3C).
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, call‐
ing any atexit() routines that might exist.
An exiting thread runs with all signals blocked. All thread termination
functions, including cancellation cleanup handlers and thread-specific
data destructor functions, are called with all signals blocked.
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 cancella‐
tion cleanup handler or destructor function that was invoked as a
result of either 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 vari‐
ables 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 behavior is as if the implementation called exit()
with a 0 argument at thread termination time.
RETURN VALUES
The pthread_exit() function cannot return to its caller.
ERRORS
No errors are defined.
