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 | |
21 * | |
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. | |
24 * | |
25 * The current implementation remembers all file names ever used. | |
