922 | (REALVALUE BUFFER CURRENT-ALIST-ELEMENT . DEFAULT-VALUE). | |
923 | ||
ce7d8eec KH |
924 | The cons-like structure is for historical reasons; it might be better |
925 | to just put these elements into the struct, now. | |
926 | ||
7d65f1c2 KH |
927 | BUFFER is the last buffer for which this symbol's value was |
928 | made up to date. | |
929 | ||
930 | CURRENT-ALIST-ELEMENT is a pointer to an element of BUFFER's | |
931 | local_var_alist, that being the element whose car is this | |
932 | variable. Or it can be a pointer to the | |
933 | (CURRENT-ALIST-ELEMENT . DEFAULT-VALUE), | |
934 | if BUFFER does not have an element in its alist for this | |
935 | variable (that is, if BUFFER sees the default value of this | |
936 | variable). | |
937 | ||
938 | If we want to examine or set the value and BUFFER is current, | |
99a3d506 | 939 | we just examine or set REALVALUE. If BUFFER is not current, we |
7d65f1c2 KH |
940 | store the current REALVALUE value into CURRENT-ALIST-ELEMENT, |
941 | then find the appropriate alist element for the buffer now | |
942 | current and set up CURRENT-ALIST-ELEMENT. Then we set | |
943 | REALVALUE out of that element, and store into BUFFER. | |
944 | ||
945 | If we are setting the variable and the current buffer does not | |
946 | have an alist entry for this variable, an alist entry is | |
947 | created. | |
948 | ||
949 | Note that REALVALUE can be a forwarding pointer. Each time it | |
950 | is examined or set, forwarding must be done. Each time we | |
951 | switch buffers, buffer-local variables which forward into C | |
952 | variables are swapped immediately, so the C code can assume | |
953 | that they are always up to date. | |

956 | use the same substructure. The difference is that with the latter, | |
957 | merely setting the variable while some buffer is current | |
958 | does not cause that buffer to have its own local value of this variable. | |
