Failed to post event by kdPostWindowEventQNX

Hi, everyone!
I want to post an event from a thread to the window(or thread) that created by kdCreateWindow.The environmoment of 
platform is QNX 6.4.0 and HP(x86)PC. The process is: 
1.EGL get display (ok)
2.EGL initialize(ok)
3.choose config by EGL(ok)
4.kdCreateWindow(ok)
5.kdRealizeWindow(ok)
6.kdThreadCreate(ok)
 6.1 kdCreateEvent(ok)
 6.2 set event data(0k)
 6.3 kdPostWindowEventQNX(NG)
7.kdWaitEvent(event nothing)
※6.1 6.2and 6.3 is sub thread process

6.3error id is 31(KD_EOPNOTSUPP)operation not supported.

My question:
1.How to clear the error?
2.There is another method to post a event from thread to window(or thread)?

Re: Failed to post event by kdPostWindowEventQNX

kdPostWindowEventQNX will return KD_EOPNOTSUPP if the event type is not one of KD_EVENT_WINDOW_CLOSE, KD_
EVENT_WINDOW_REDRAW, KD_EVENT_WINDOW_FOCUS, KD_EVENT_WINDOWPROPERTY_CHANGE, KD_EVENT_STATE, KD_EVENT_INPUT, KD_
EVENT_INPUT_JOG, KD_EVENT_INPUT_POINTER, KD_EVENT_INPUT_STICK, KD_EVENT_USER, KD_QNX_EVENT_KEYBOARD, KD_QNX_
EVENT_WINDOW_CREATE, KD_QNX_EVENT_WINDOW_REALIZE, KD_QNX_EVENT_WINDOW_PROPERTY, or KD_QNX_EVENT_WINDOW_CLOSE.

To answer your specific questions, the error code returned by kdGetError is not changed unless kdSetError is called or 
another OpenKODE function sets the value as specified for that function.

kdPostThreadEvent would normally be used to post events from one thread to another. However, this function isn't 
implemented in QNX yet, so your best be is to stick with kdPostWindowEventQNX for now.
