- Sub: Interrupts and 2.0ß9
-
- I need assistance regarding interrupts and MacApp 2.0ß9. I have attempted to
- use the TN#180 VBL example modified by using the UBusyCursor.p WatchTask
- techniques as a guide. I can not avoid crashing with system errors 11 or 12 in
- the MacApp debugger.
-
- Does any one have a small code example that shows either VBL, Time Manager, or
- I/O completion interrupt usage within the 2.0ß9 framework? If not, could you
- give me insight on any special needs MacApp might require to allow interrupt
- level processing?
-
- I have simply implemented VInstall() in TMyApplication.IApplication, VRemove()
- in TMyApplication.Free, and a simple VBL task (increment counter, posted an
- event, reset the VBL interval). The TMyApplication.DoHandleEvent() method does
- an inherited TApplication.Beep() upon receipt of the event posted by the VBL
- task. Are there better choices?
