Node:Buffer Walk Through, Next:More Complex, Previous:Writing Defuns, Up:Top
In this chapter we study in detail several of the functions used in GNU Emacs. This is called a "walk-through". These functions are used as examples of Lisp code, but are not imaginary examples; with the exception of the first, simplified function definition, these functions show the actual code used in GNU Emacs. You can learn a great deal from these definitions. The functions described here are all related to buffers. Later, we will study other functions.
goto-char,
point-min, and push-mark.
beginning-of-buffer.
save-excursion and
insert-buffer-substring.
