Debugging with GDB (September 2007)

262 Debugging with GDB
^Z^Zerror
This annotation occurs right b e fore GDB responds to an error.
Quit and error annotations indicate that any annotations which GDB was in the middle
of may end abruptly. For example, if a value-history-begin annotation is followed by a
error, one cannot expect to rec eive the matching value-history-end. One cannot expect
not to receive it either; however, an error annotation does not necessarily mean that GDB
is immediately returning all the way to the top level.
A quit or error annotation may be preceded by
^Z^Zerror-begin
Any output b e twe en that and the quit or error annotation is the error message.
Warning messages are not yet annotated.
20.8 Information on breakpoints
The output from the info breakpoints command is annotated as follows:
^Z^Zbreakpoints-headers
header-entry
^Z^Zbreakpoints-table
where header-entry has the s ame syntax as an entry (see below) but instead of containing
data, it contains strings which are intended to convey the meaning of each field to the user.
This is followed by any number of entries. If a field does not apply for this entry, it is
omitted. Fields m ay contain trailing whitespace. Each entry consists of:
^Z^Zrecord
^Z^Zfield 0
number
^Z^Zfield 1
type
^Z^Zfield 2
disposition
^Z^Zfield 3
enable
^Z^Zfield 4
address
^Z^Zfield 5
what
^Z^Zfield 6
frame
^Z^Zfield 7
condition
^Z^Zfield 8
ignore-count
^Z^Zfield 9
commands
Note that address is intended for user consumption—the syntax varies depending on the
language.
The output ends with
^Z^Zbreakpoints-table-end
