742 | ||

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

746 | BUFFER is the last buffer for which this symbol's value was |

748 | ||
749 | CURRENT-ALIST-ELEMENT is a pointer to an element of BUFFER's | |
750 | local_var_alist, that being the element whose car is this | |
751 | variable. Or it can be a pointer to the | |
752 | (CURRENT-ALIST-ELEMENT . DEFAULT-VALUE), | |
753 | if BUFFER does not have an element in its alist for this | |
754 | variable (that is, if BUFFER sees the default value of this | |
755 | variable). | |
756 | ||
757 | If we want to examine or set the value and BUFFER is current, | |
99a3d506 | 758 | we just examine or set REALVALUE. If BUFFER is not current, we |
7d65f1c2 KH |
759 | store the current REALVALUE value into CURRENT-ALIST-ELEMENT, |
760 | then find the appropriate alist element for the buffer now | |
761 | current and set up CURRENT-ALIST-ELEMENT. Then we set | |
762 | REALVALUE out of that element, and store into BUFFER. | |
763 | ||
764 | If we are setting the variable and the current buffer does not | |
765 | have an alist entry for this variable, an alist entry is | |
766 | created. | |
767 | ||
768 | Note that REALVALUE can be a forwarding pointer. Each time it | |
769 | is examined or set, forwarding must be done. Each time we | |
770 | switch buffers, buffer-local variables which forward into C | |
771 | variables are swapped immediately, so the C code can assume | |

775 | use the same substructure. The difference is that with the latter, | |
