HP gnu source-level debugger 5992-4701 manual Errors, Information on breakpoints

^Z^Zpre-prompt ^Z^Zprompt ^Z^Zpost-prompt

The input types are:
prompt	When GDB is prompting for a command (the main GDB
	prompt).
commands	When GDB prompts for a set of commands, like in the
	commands command. The annotations are repeated for
	each command which is input.
overload-choice	When GDB wants the user to select between various
	overloaded functions.
query	When GDB wants the user to confirm a potentially
	dangerous operation.
prompt-for-continue	When GDB is asking the user to press return to continue.
	Note: Don't expect this to work well; instead use set
	height 0 to disable prompting. This is because the
	counting of lines is buggy in the presence of annotations.

20.7 Errors

^Z^Zquit

This annotation occurs right before GDB responds to an interrupt.

^Z^Zerror

This annotation occurs right before 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-beginannotation is followed by a error, one cannot expect to receive 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 between that and the quit or error annotation is the error message.

Warning messages are not yet annotated.
