812 | The actual contents resemble a cons cell which starts a list like this: | |
813 | (REALVALUE BUFFER CURRENT-ALIST-ELEMENT . DEFAULT-VALUE). | |
814 | ||
ce7d8eec KH |
815 | The cons-like structure is for historical reasons; it might be better |
816 | to just put these elements into the struct, now. | |
817 | ||
7d65f1c2 KH |
818 | BUFFER is the last buffer for which this symbol's value was |
819 | made up to date. | |
820 | ||
821 | CURRENT-ALIST-ELEMENT is a pointer to an element of BUFFER's | |
822 | local_var_alist, that being the element whose car is this | |
823 | variable. Or it can be a pointer to the | |
824 | (CURRENT-ALIST-ELEMENT . DEFAULT-VALUE), | |
825 | if BUFFER does not have an element in its alist for this | |
826 | variable (that is, if BUFFER sees the default value of this | |
827 | variable). | |
828 | ||
829 | If we want to examine or set the value and BUFFER is current, | |
99a3d506 | 830 | we just examine or set REALVALUE. If BUFFER is not current, we |
7d65f1c2 KH |
831 | store the current REALVALUE value into CURRENT-ALIST-ELEMENT, |
832 | then find the appropriate alist element for the buffer now | |
833 | current and set up CURRENT-ALIST-ELEMENT. Then we set | |
834 | REALVALUE out of that element, and store into BUFFER. | |
835 | ||
836 | If we are setting the variable and the current buffer does not | |
837 | have an alist entry for this variable, an alist entry is | |
838 | created. | |
839 | ||
840 | Note that REALVALUE can be a forwarding pointer. Each time it | |
841 | is examined or set, forwarding must be done. Each time we | |
842 | switch buffers, buffer-local variables which forward into C | |
843 | variables are swapped immediately, so the C code can assume | |
844 | that they are always up to date. | |
845 | ||
846 | Lisp_Misc_Buffer_Local_Value and Lisp_Misc_Some_Buffer_Local_Value | |
847 | use the same substructure. The difference is that with the latter, | |
848 | merely setting the variable while some buffer is current | |
849 | does not cause that buffer to have its own local value of this variable. | |
850 | Only make-local-variable does that. */ | |
