pthread_exit(3T)pthread_exit(3T)NAMEpthread_exit() - cause the calling thread to terminate
SYNOPSISPARAMETERS
value_ptr The calling thread's exit status.
DESCRIPTION
terminates the calling thread. The calling thread returns an exit sta‐
tus in value_ptr. This value is returned to a joining thread calling
on the terminating thread. Only threads created with the detachstate
attribute value can return an exit status to The exit status of a
detached thread is lost when the thread terminates.
When a thread terminates, process-shared resources are not released.
Examples of process-shared resources include mutexes, condition vari‐
ables, semaphores, message queue descriptors, and file descriptors.
The routines are not called when a thread terminates as this is a
process termination action.
An implicit call to is made when a thread returns from its start rou‐
tine. The function's return value serves as the thread's exit status
(see pthread_create(3T)). If the main thread returns from without
calling the process will exit using the return value from as the exit
status. If the main thread calls the process will continue executing
until the last thread terminates or a thread calls After the last
thread in the process terminates, the process will exit with an exit
status of zero.
Any installed cancellation cleanup handlers will be popped and executed
in the reverse order that they were installed. After the cancellation
cleanup handlers have been executed, if the thread has any non-NULL
thread-specific data values with associated destructor functions, the
destructor functions are called. The order in which these destructor
functions are called is unspecified.
Calling from a cancellation cleanup handler or destructor function that
was invoked because of thread termination results in undefined behav‐
ior.
After a thread has terminated, the result of access to local (auto)
variables of the thread is undefined. The terminating thread should
not use local variables for the value_ptr parameter value.
RETURN VALUE
None.
ERRORS
None, this function does not return.
