This function requests FUNCTION-NAME to invoke the debugger each
time it is called. It works by inserting the form `(debug
'debug)' into the function definition as the first form.

- - Command: cancel-debug-on-entry FUNCTION-NAME

This function undoes the effect of `debug-on-entry' on
FUNCTION-NAME. When called interactively, it prompts for
FUNCTION-NAME in the minibuffer. If FUNCTION-NAME is `nil' or the
additional form can be evaluated and its value ignored. (If the value
of `(debug)' isn't ignored, it will alter the execution of the
program!) The most common suitable places are inside a `progn' or an

the debugger (with the `q' command) when you are finished with it.
Exiting the debugger gets out of the recursive edit and kills the
backtrace buffer.
Here we describe fully the function used to invoke the debugger.
- - Function: debug &rest DEBUGGER-ARGS
+ - Function: debug &rest debugger-args
This function enters the debugger. It switches buffers to a buffer
named `*Backtrace*' (or `*Backtrace*<2>' if it is the second
recursive entry to the debugger, etc.), and fills it with

description of `debug'.
- - Command: backtrace &optional STREAM DETAILED

This function prints a trace of Lisp function calls currently
active. This is the function used by `debug' to fill up the
`*Backtrace*' buffer. It is written in C, since it must have

The `d' command in the debugger works by setting this variable.
- - Function: backtrace-debug LEVEL FLAG
+ - Function: backtrace-debug level flag
This function sets the debug-on-exit flag of the stack frame LEVEL
levels down the stack, giving it the value FLAG. If FLAG is
non-`nil', this will cause the debugger to be entered when that
another global variable is that the data will never carry over to a
subsequent command invocation.
- - Function: backtrace-frame FRAME-NUMBER
+ - Function: backtrace-frame frame-number
The function `backtrace-frame' is intended for use in Lisp
debuggers. It returns information about what computation is
happening in the stack frame FRAME-NUMBER levels down.
