ipcWait

ipcWait( 
o_childId 
[ x_interval ] 
[ x_timeOut ] 
) 
=> t

Causes the parent process to suspend until the child terminates.

This function is like the sleep function in that it allows incoming messages to take effect while waiting.

o_childId	Child process handle.
x_interval	The interval at which “Waiting for ... to terminate” message is printed. Default is 30 seconds.
x_timeOut	Time beyond which this call should not block. The default timeout value is 1000000 seconds and the maximum is 2592000 seconds (= 30 days).

`t`	Always returns `t`.

      cid = ipcBeginProcess("sleep 30")

      ipcWait(cid) 
            ; Suspends here until the child process terminates
