635 | ||

636 | The cons-like structure is for historical reasons; it might be better |
637 | to just put these elements into the struct, now. | |
638 | ||

639 | BUFFER is the last buffer for which this symbol's value was |
640 | made up to date. | |
641 | ||
642 | CURRENT-ALIST-ELEMENT is a pointer to an element of BUFFER's | |
643 | local_var_alist, that being the element whose car is this | |
644 | variable. Or it can be a pointer to the | |
645 | (CURRENT-ALIST-ELEMENT . DEFAULT-VALUE), | |
646 | if BUFFER does not have an element in its alist for this | |
647 | variable (that is, if BUFFER sees the default value of this | |
648 | variable). | |
649 | ||
650 | If we want to examine or set the value and BUFFER is current, | |
99a3d506 | 651 | we just examine or set REALVALUE. If BUFFER is not current, we |
7d65f1c2 KH |
652 | store the current REALVALUE value into CURRENT-ALIST-ELEMENT, |
653 | then find the appropriate alist element for the buffer now | |
654 | current and set up CURRENT-ALIST-ELEMENT. Then we set | |
655 | REALVALUE out of that element, and store into BUFFER. | |
656 | ||
657 | If we are setting the variable and the current buffer does not | |
658 | have an alist entry for this variable, an alist entry is | |
659 | created. | |
660 | ||
661 | Note that REALVALUE can be a forwarding pointer. Each time it | |
662 | is examined or set, forwarding must be done. Each time we | |
663 | switch buffers, buffer-local variables which forward into C | |
664 | variables are swapped immediately, so the C code can assume | |
665 | that they are always up to date. | |

667 | Lisp_Misc_Buffer_Local_Value and Lisp_Misc_Some_Buffer_Local_Value | |
668 | use the same substructure. The difference is that with the latter, | |
669 | merely setting the variable while some buffer is current | |
