Each prompt is composed as a prefix, a prompt - and a suffix. The prompt to be displayed at any given time is the - one on top of the stack. A stack is necessary because of cases in - which the execution of a gdb command requires further input from - the user, like for instance 'commands' for breakpoints and - 'actions' for tracepoints. In these cases, the prompt is '>' and - gdb should process input using the asynchronous readline interface - and the event loop. In order to achieve this, we need to save - somewhere the state of GDB, i.e. that it is processing user input - as part of a command and not as part of the top level command loop. - The prompt stack represents part of the saved state. Another part - would be the function that readline would invoke after a whole line - of input has ben entered. This second piece would be something - like, for instance, where to return within the code for the actions - commands after a line has been read. This latter portion has not - beeen implemented yet. The need for a 3-part prompt arises from - the annotation level. When this is set to 2, the prompt is - actually composed of a prefix, the prompt itself and a suffix. */ - -/* At any particular time there will be always at least one prompt on - the stack, the one being currently displayed by gdb.

At this - time, this is the only use of the prompt stack. Resetting annotate - to 0 or 1, pops the top of the stack, resetting its size to one - element. The MAXPROMPTS limit is safe, for now.
