where
If GDB prints some information about where the frame is from (which library, which load segment, etc.; currently only done on the RS/6000), it is annotated with
Then, if source is to be actually displayed for this frame (for example, this is not true for output from the backtrace command), then a source annotation (see “Displaying source” (page 304)) is displayed. Unlike most annotations, this is output instead of the normal text which would be output, not in addition.
20.5 Displays
When GDB is told to display something using the display command, the results of the display are annotated:
value
where number is the number of the display,
20.6 Annotation for GDB input
When GDB prompts for input, it annotates this fact so it is possible to know when to send output, when the output from a given command is over, etc.
Different kinds of input each have a different input type. Each input type has three annotations: a preannotation, which denotes the beginning of any prompt which is being output, a plain annotation, which denotes the end of the prompt, and then a post- annotation which denotes the end of any echo which may (or may not) be associated with the input. For example, the prompt input type features the following annotations:
