3 * VIM - Vi IMproved by Bram Moolenaar
5 * Do ":help uganda" in Vim to read copying and usage conditions.
6 * Do ":help credits" in Vim to see a list of people who contributed.
7 * See README.txt for an overview of the Vim source code.
11 * buffer.c: functions for dealing with the buffer structure
15 * The buffer list is a double linked list of all buffers.
16 * Each buffer can be in one of these states:
17 * never loaded: BF_NEVERLOADED is set, only the file name is valid
18 * not loaded: b_ml.ml_mfp == NULL, no memfile allocated
19 * hidden: b_nwindows == 0, loaded but not displayed in a window
20 * normal: loaded and displayed in a window
22 * Instead of storing file names all over the place, each file name is
23 * stored in the buffer list. It can be referenced by a number.
25 * The current implementation remembers all file names ever used.
