RE: Suggestion: array-of-structures slices

[Atwood, Robert C]

You must have read my mind, I would like to see this feature, I often found
it useful in cvd debugger (only) on an SGI machine; but in my understanding
-- would this not require the feature to be implemented in the underlying
debugger? the command  display address@hidden is a gdb command; and ddd somehow
gets the output of it and puts it into the display right?

If the underlying debugger would return that slice could DDD display it?
Is there an existing (underlying) debugger for linux/gnu platform that does
this?
Should this be a question on the gdb project list?

Thanks
Robert

Hello!

DDD can plot values from a slice of an array - IF that array is made up of 
base datatypes. It cannot plot slices if the array is made of structures,
and 
I believe it would be very useful if it could!

Example: assume we have an array A[100] made up of structures like this:

typedef struct {
    int x;
    int y;
};

I think it would be good if DDD could plot/display the string of A.x'es. The

syntax describing this would probably best be: (address@hidden).x   (which
currently 
just displays A[0].x). This means reading an array of 100 elements, starting

from A[0] with a stride equal to sizeof(A[0]). Currently DDD can only read 
with a stride of sizeof(x), if we were to say (A[0].x)@100, which reads 
alternating x'es and y'es.

Thank you for taking the time to read this!

Deepest regards,
Mihai Basa
