-.SH NAME
-pthread_join \- join with a terminated thread
-.SH LIBRARY
-POSIX threads library
-.RI ( libpthread ", " \-lpthread )
-.SH SYNOPSIS
-.nf
-.B #include <pthread.h>
-.P
-.BI "int pthread_join(pthread_t " thread ", void **" retval );
-.fi
-.SH DESCRIPTION
-The
-.BR pthread_join ()
-function waits for the thread specified by
-.I thread
-to terminate.
-If that thread has already terminated, then
-.BR pthread_join ()
-returns immediately.
-The thread specified by
-.I thread
-must be joinable.
-.P
-If
-.I retval
-is not NULL, then
-.BR pthread_join ()
-copies the exit status of the target thread
-(i.e., the value that the target thread supplied to
-.BR pthread_exit (3))
-into the location pointed to by
-.IR retval .
-If the target thread was canceled, then
-.B PTHREAD_CANCELED
-is placed in the location pointed to by
-.IR retval .
-.P
-If multiple threads simultaneously try to join with the same thread,
-the results are undefined.
-If the thread calling
-.BR pthread_join ()
-is canceled, then the target thread will remain joinable
-(i.e., it will not be detached).
-.SH RETURN VALUE
-On success,
-.BR pthread_join ()
-returns 0;
-on error, it returns an error number.
-.SH ERRORS
-.TP
-.B EDEADLK
-A deadlock was detected
-.\" The following verified by testing on glibc 2.8/NPTL:
-(e.g., two threads tried to join with each other);
-or
-.\" The following verified by testing on glibc 2.8/NPTL:
-.I thread
-specifies the calling thread.
-.TP
-.B EINVAL
-.I thread
-is not a joinable thread.
-.TP
-.B EINVAL
-Another thread is already waiting to join with this thread.
-.\" POSIX.1-2001 does not specify this error case.
-.TP
-.B ESRCH
-No thread with the ID
-.I thread
-could be found.

-.SH STANDARDS

-.SH HISTORY
-POSIX.1-2001.
-.SH NOTES
-After a successful call to
-.BR pthread_join (),
-the caller is guaranteed that the target thread has terminated.
-The caller may then choose to do any clean-up that is required
-after termination of the thread (e.g., freeing memory or other
-resources that were allocated to the target thread).
-.P
-Joining with a thread that has previously been joined results in
-undefined behavior.
-.P
-Failure to join with a thread that is joinable
-(i.e., one that is not detached),
-produces a "zombie thread".
-Avoid doing this,
-since each zombie thread consumes some system resources,
-and when enough zombie threads have accumulated,
-it will no longer be possible to create new threads (or processes).
-.P
-There is no pthreads analog of
-.IR "waitpid(\-1,\ &status,\ 0)" ,
-that is, "join with any terminated thread".
-If you believe you need this functionality,
-you probably need to rethink your application design.
-.P
-All of the threads in a process are peers:
-any thread can join with any other thread in the process.

-.BR pthread_create (3).
