625 81fe2ccc1207 updated for version 7.0179 vimboss parents: 619 diff changeset	16 * text lines. The memfile functions are used to store the information in
81fe2ccc1207 updated for version 7.0179 vimboss parents: 619 diff changeset	17 * blocks of memory, backed up by a file. The structure of the information is
81fe2ccc1207 updated for version 7.0179 vimboss parents: 619 diff changeset	18 * a tree. The root of the tree is a pointer block. The leaves of the tree
81fe2ccc1207 updated for version 7.0179 vimboss parents: 619 diff changeset	19 * are data blocks. In between may be several layers of pointer blocks,
81fe2ccc1207 updated for version 7.0179 vimboss parents: 619 diff changeset	20 * forming branches.

3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	22 * Three types of blocks are used:
3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	23 * - Block nr 0 contains information for recovery
3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	24 * - Pointer blocks contain list of pointers to other blocks.
3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	25 * - Data blocks contain the actual text.
3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	26 *
3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	27 * Block nr 0 contains the block0 structure (see below).

3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	29 * Block nr 1 is the first pointer block. It is the root of the tree.
3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	30 * Other pointer blocks are branches.
3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	31 *
3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	32 * If a line is too big to fit in a single page, the block containing that
3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	33 * line is made big enough to hold the line. It may span several pages.
3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	34 * Otherwise all blocks are one page.

3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	36 * A data block that was filled when starting to edit a file and was not
3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	37 * changed since then, can have a negative block number. This means that it
3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	38 * has not yet been assigned a place in the file. When recovering, the lines
3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	39 * in this data block can be read from the original file. When the block is
3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	40 * changed (lines appended/deleted/changed) or when it is flushed it gets a
3fc0f57ecb91 updated for version 7.0001 vimboss parents: diff changeset	41 * positive number. Use mf_trans_del() to get the new number, before calling
