| 15 * memline.c: Contains the functions for appending, deleting and changing the | |
| 625 | 16 * text lines. The memfile functions are used to store the information in |
| 17 * blocks of memory, backed up by a file. The structure of the information is | |
| 18 * a tree. The root of the tree is a pointer block. The leaves of the tree | |
| 19 * are data blocks. In between may be several layers of pointer blocks, | |
| 20 * forming branches. | |
| 7 | 21 * |
| 22 * Three types of blocks are used: | |
| 23 * - Block nr 0 contains information for recovery | |
| 24 * - Pointer blocks contain list of pointers to other blocks. | |
| 25 * - Data blocks contain the actual text. | |
| 26 * | |
| 27 * Block nr 0 contains the block0 structure (see below). | |
| 28 * | |
| 29 * Block nr 1 is the first pointer block. It is the root of the tree. | |
| 30 * Other pointer blocks are branches. | |
| 31 * | |
| 32 * If a line is too big to fit in a single page, the block containing that | |
| 33 * line is made big enough to hold the line. It may span several pages. | |
| 34 * Otherwise all blocks are one page. | |
| 35 * | |
| 36 * A data block that was filled when starting to edit a file and was not | |
| 37 * changed since then, can have a negative block number. This means that it | |
| 38 * has not yet been assigned a place in the file. When recovering, the lines | |
| 39 * in this data block can be read from the original file. When the block is | |
| 40 * changed (lines appended/deleted/changed) or when it is flushed it gets a | |
| 41 * positive number. Use mf_trans_del() to get the new number, before calling | |
| 42 * mf_get(). | |
