My main event loop looks like this:
static void AppEventLoop (void) {
EventType event;
UInt16 error = 0;
do {
WinHandle winH = WinGetActiveWindow ();
if ( winH )
ErrFatalDisplayIf ( ! WinValidateHandle ( winH ), "Invalid window" );
EvtGetEvent ( &event, eventWaitTicks );
if ( ! SysHandleEvent ( &event ) ) {
if ( ! MenuHandleEvent ( 0, &event, &error ) ) {
if ( ! AppHandleEvent ( &event ) ) {
etc...
Once I've draw my main form, if I try to do an EvtGetEvent in this
loop, I get the message "YourApp has just read from an unallocated
chunk of memory" on the call to EvtGetEvent. The stack trace shows
(in order) AppEventLoop, SysGetEvent, WinSetDrawWindow,
WinValidateHandle (where it blows up). Oddly, the stack trace doesn't
show EvtGetEvent.
This says to me that WinValidateHandle is blowing up, but the handle
validates OK immediately prior to this happening. (Yes, I have
ERROR_CHECK_LEVEL turned on).
Does anyone have any interesting suggestions, observations,
comments, anything that might help me track this problem down? Thanks.
This is with POSE 3.0a7, 3.5 EZDebug ROM, Mac OS 9.0.2.

Steve Mann
