Chapter 27. gdb Annotations 279
When printing an array, gdb annotates it as follows:
^Z^Zarray-section-begin
array-index value-flags
where
array-index
is the index of the first element being annotated and
value-flags
has the same
meaning as in a
value-history-begin
annotation. This is followed by any number of elements,
where is element can be either a single element:
, whitespace
; omitted for the first element
the-value
^Z^Zelt
or a repeated element
, whitespace
; omitted for the first element
the-value
^Z^Zelt-rep
number-of-repetitions
repetition-string
^Z^Zelt-rep-end
In both cases,
the-value
is the output for the value of the element and
whitespace
can contain
spaces, tabs, and newlines. In the repeated case,
number-of-repetitions
is the number of consec-
utive array elements which contain that value, and
repetition-string
is a string which is designed
to convey to the user that repetition is being depicted.
Once all the array elements have been output, the array annotation is ended with
^Z^Zarray-section-end
27.4. Frames
Whenever gdb prints a frame, it annotates it. For example, this applies to frames printed when gdb
stops, output from commands such as
backtrace
or
up
, etc.
The frame annotation begins with
^Z^Zframe-begin
level address
level-string
where
level
is the number of the frame (0 is the innermost frame, and other frames have positive
numbers),
address
is the address of the code executing in that frame, and
level-string
is a string
designed to convey the level to the user.
address
is in the form
0x
followed by one or more lowercase
hex digits (note that this does not depend on the language). The frame ends with
^Z^Zframe-end
