934 | ||
ce7d8eec KH |
935 | The cons-like structure is for historical reasons; it might be better |
936 | to just put these elements into the struct, now. | |
937 | ||
7d65f1c2 KH |
938 | BUFFER is the last buffer for which this symbol's value was |
939 | made up to date. | |
940 | ||
941 | CURRENT-ALIST-ELEMENT is a pointer to an element of BUFFER's | |
942 | local_var_alist, that being the element whose car is this | |
943 | variable. Or it can be a pointer to the | |
944 | (CURRENT-ALIST-ELEMENT . DEFAULT-VALUE), | |
945 | if BUFFER does not have an element in its alist for this | |
946 | variable (that is, if BUFFER sees the default value of this | |
947 | variable). | |
948 | ||
949 | If we want to examine or set the value and BUFFER is current, | |
99a3d506 | 950 | we just examine or set REALVALUE. If BUFFER is not current, we |
7d65f1c2 KH |
951 | store the current REALVALUE value into CURRENT-ALIST-ELEMENT, |
952 | then find the appropriate alist element for the buffer now | |
953 | current and set up CURRENT-ALIST-ELEMENT. Then we set | |
954 | REALVALUE out of that element, and store into BUFFER. | |
955 | ||
956 | If we are setting the variable and the current buffer does not | |
957 | have an alist entry for this variable, an alist entry is | |
958 | created. | |
959 | ||
960 | Note that REALVALUE can be a forwarding pointer. Each time it | |
961 | is examined or set, forwarding must be done. Each time we | |
962 | switch buffers, buffer-local variables which forward into C | |
