pthread_exit()

terminate thread 

Function


SYNOPSIS

#include <pthread.h>

void pthread_exit(void *status);


DESCRIPTION

The pthread_exit() function terminates the calling thread and makes the value status available to any successful join with the terminating thread. 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 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 performs any process-level cleanup actions, including, but not limited to, calling any 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 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. References to local variables of the exiting thread should not be used for the pthread_exit() status parameter value.

The process exits with an exit status of 0 after the last thread has been terminated. The behavior is as if exit() was called with a zero argument.
