610 | ||

611 | The cons-like structure is for historical reasons; it might be better |
612 | to just put these elements into the struct, now. | |
613 | ||
7d65f1c2 KH |
614 | BUFFER is the last buffer for which this symbol's value was |
615 | made up to date. | |
616 | ||
617 | CURRENT-ALIST-ELEMENT is a pointer to an element of BUFFER's | |
618 | local_var_alist, that being the element whose car is this | |
619 | variable. Or it can be a pointer to the | |
620 | (CURRENT-ALIST-ELEMENT . DEFAULT-VALUE), | |
621 | if BUFFER does not have an element in its alist for this | |
622 | variable (that is, if BUFFER sees the default value of this | |
623 | variable). | |
624 | ||
625 | If we want to examine or set the value and BUFFER is current, | |
99a3d506 | 626 | we just examine or set REALVALUE. If BUFFER is not current, we |
7d65f1c2 KH |
627 | store the current REALVALUE value into CURRENT-ALIST-ELEMENT, |
628 | then find the appropriate alist element for the buffer now | |
629 | current and set up CURRENT-ALIST-ELEMENT. Then we set | |
630 | REALVALUE out of that element, and store into BUFFER. | |
631 | ||
632 | If we are setting the variable and the current buffer does not | |
633 | have an alist entry for this variable, an alist entry is | |
634 | created. | |
635 | ||
636 | Note that REALVALUE can be a forwarding pointer. Each time it | |
637 | is examined or set, forwarding must be done. Each time we | |
638 | switch buffers, buffer-local variables which forward into C | |
639 | variables are swapped immediately, so the C code can assume | |
640 | that they are always up to date. | |
641 | ||
642 | Lisp_Misc_Buffer_Local_Value and Lisp_Misc_Some_Buffer_Local_Value | |
643 | use the same substructure. The difference is that with the latter, | |
644 | merely setting the variable while some buffer is current | |
