Usage
The threadwait function waits for the given thread to
complete execution, and stops execution of the current
thread (the one calling threadwait) until the given thread
completes. The syntax for its use is
success = threadwait(handle)
where handle is the value returned by threadnew and success
is a logical vaariable that will be 1 if the wait was
successful or 0 if the wait times out. By default, the wait
is indefinite. It is better to use the following form of the
function
success = threadwait(handle,timeout)
where timeout is the amount of time (in milliseconds) for
the threadwait function to wait before a timeout occurs. If
the threadwait function succeeds, then the return value is a
logical 1, and if it fails, the return value is a logical 0.
Note that you can call threadwait multiple times on a
thread, and if the thread is completed, each one will
succeed.
Example
Here we lauch the sleep function in a thread with a time
delay of 10 seconds. This means that the thread function
will not complete until 10 seconds have elapsed. When we
call threadwait on this thread with a short timeout, it
fails, but not when the timeout is long enough to capture
the end of the function call.
--> a = threadnew;
--> threadstart(a,'sleep',0,10); % start a thread that
will sleep for 10
--> threadwait(a,2000) % 2 second wait is not
long enough
ans =
0
--> threadwait(a,10000) % 10 second wait is long
enough
ans =
1
--> threadfree(a)
