Re: DDD-3.3 and vxWorks [SOLVED PARTIALLY]

[Shash Chatterjee]

OK...since nobody replied....either this was a really dumb question or 
not many on this list know.....

So...to attach to a vxWorks task, on the gdb console do "tcl 
activeTaskNameMap" and then do "attach 0xXXXXXX" (where XXXXXX is as 
returned for the task to be debugged as returned by the previous 
command)".  You can automate this partially by defining the following 
resource:

Ddd*consoleButtons: \
  tcl activeTaskNameMap // VxWorks Task List

I am considering changing the DDD source in file.C 
(gdbUpdateProcesses(...) or update_processes(...) to make them vxWorks 
aware and instead of sending a "ps" command to the Unix shell, do a 
command to the inferior debugger.  But more when I have time.....any 
pointers as to how to write-to/read-from the inferior debugger most welcome!
