Any +cancellation cleanup handlers that have been pushed and not yet popped +shall be 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 shall 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, +calling any +\fIatexit\fR() +routines that may exist. +.P +An implicit call to +\fIpthread_exit\fR() +is made when a thread other than the thread in which +\fImain\fR() +was first invoked returns from the start routine that was used to +create it. The function's return value shall serve as the thread's +exit status. +.P +The behavior of +\fIpthread_exit\fR() +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 +\fIpthread_exit\fR(). +.P +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 +\fIpthread_exit\fR() +.IR value_ptr +parameter value. +.P +The process shall exit with an exit status of 0 after the last thread +has been terminated. The behavior shall be as if the implementation +called +\fIexit\fR() +with a zero argument at thread termination time. +.SH "RETURN VALUE" +The +\fIpthread_exit\fR() +function cannot return to its caller. +.SH ERRORS +No errors are defined. +.LP +.IR "The following sections are informative." +.SH EXAMPLES +None. +.SH "APPLICATION USAGE" +None. +.SH RATIONALE +The normal mechanism by which a thread terminates is to return from the +routine that was specified in the +\fIpthread_create\fR() +call that started it. The +\fIpthread_exit\fR() +function provides the capability for a thread to terminate without +requiring a return from the start routine of that thread, thereby +providing a function analogous to +\fIexit\fR(). +.P +Regardless of the method of thread termination, any +cancellation cleanup handlers that have been pushed and not yet popped +are executed, and the destructors for any existing thread-specific data +are executed. This volume of POSIX.1\(hy2008 requires that cancellation cleanup handlers be +popped and called in order. After all cancellation cleanup handlers have +been executed, thread-specific data destructors are called, in an +unspecified order, for each item of thread-specific data that exists in +the thread. This ordering is necessary because cancellation cleanup +handlers may rely on thread-specific data. +.P +As the meaning of the status is determined by the application (except +when the thread has been canceled, in which case it is +PTHREAD_CANCELED), +the implementation has no idea what an illegal status value is, which +is why no address error checking is done. +.SH "FUTURE DIRECTIONS" +None. +.SH "SEE ALSO" +.IR "\fIexit\fR\^(\|)", +.IR "\fIpthread_create\fR\^(\|)", +.IR "\fIpthread_join\fR\^(\|)" +.P +The Base Definitions volume of POSIX.1\(hy2008, +.IR "\fB<pthread.h>\fP" +.SH COPYRIGHT +Portions of this text are reprinted and reproduced in electronic form +from IEEE Std 1003.1, 2013 Edition, Standard for Information Technology +-- Portable Operating System Interface (POSIX), The Open Group Base +Specifications Issue 7, Copyright (C) 2013 by the Institute of +Electrical and Electronics Engineers, Inc and The Open Group. +(This is POSIX.1-2008 with the 2013 Technical Corrigendum 1 applied.)
