- What is the reason for xdb not being able to access an opaque data
- structure? If you use xdb to debug Xt/motif code and try to access
- a widget xdb gives a <<NULLSYMBOL>> which I presume means that it
- has no 'matching' data structure to map the data to. But you can
- cast many variables to C data types with xdb and it works fine.
-
- So a second part to this question would be: Can you cast a variable
- to a structure with xdb and if not why not?
-
- And how does corvallis debug motif code?
