101 | The actual contents are a cons cell which starts a list like this: |
102 | (REALVALUE BUFFER CURRENT-ALIST-ELEMENT . DEFAULT-VALUE). | |
103 | ||
104 | BUFFER is the last buffer for which this symbol's value was | |
105 | made up to date. | |
106 | ||
107 | CURRENT-ALIST-ELEMENT is a pointer to an element of BUFFER's | |
108 | local_var_alist, that being the element whose car is this | |
109 | variable. Or it can be a pointer to the | |
110 | (CURRENT-ALIST-ELEMENT . DEFAULT-VALUE), | |
111 | if BUFFER does not have an element in its alist for this | |
112 | variable (that is, if BUFFER sees the default value of this | |
113 | variable). | |
114 | ||
115 | If we want to examine or set the value and BUFFER is current, | |
116 | we just examine or set REALVALUE. If BUFFER is not current, we | |
117 | store the current REALVALUE value into CURRENT-ALIST-ELEMENT, | |
118 | then find the appropriate alist element for the buffer now | |
119 | current and set up CURRENT-ALIST-ELEMENT. Then we set | |
120 | REALVALUE out of that element, and store into BUFFER. | |
121 | ||
122 | If we are setting the variable and the current buffer does not | |
123 | have an alist entry for this variable, an alist entry is | |
124 | created. | |
125 | ||
126 | Note that REALVALUE can be a forwarding pointer. Each time it | |
bad481d4 JB |
127 | is examined or set, forwarding must be done. Each time we |
128 | switch buffers, buffer-local variables which forward into C | |
129 | variables are swapped immediately, so the C code can assume | |

820 | By convention, it should be the same as `fnname' but with S instead of F. | |
821 | It's too bad that C macros can't compute this from `fnname'. | |
822 | `minargs' should be a number, the minimum number of arguments allowed. | |
823 | `maxargs' should be a number, the maximum number of arguments allowed, | |
824 | or else MANY or UNEVALLED. | |
825 | MANY means pass a vector of evaluated arguments, | |
826 | in the form of an integer number-of-arguments | |
827 | followed by the address of a vector of Lisp_Objects | |
828 | which contains the argument values. | |
829 | UNEVALLED means pass the list of unevaluated arguments | |
830 | `prompt' says how to read arguments for an interactive call. | |
831 | This can be zero or a C string. | |
832 | Zero means that interactive calls are not allowed. | |
833 | A string is interpreted in a hairy way: | |
834 | it should contain one line for each argument to be read, terminated by \n. | |
835 | The first character of the line controls the type of parsing: | |
836 | s -- read a string. | |
837 | S -- read a symbol. | |
838 | k -- read a key sequence and return it as a string. | |
839 | a -- read a function name (symbol) with completion. | |
840 | C -- read a command name (symbol) with completion. | |
841 | v -- read a variable name (symbol) with completion. | |
842 | b -- read a buffer name (a string) with completion. | |
843 | B -- buffer name, may be existing buffer or may not be. | |
844 | f -- read a file name, file must exist. | |
845 | F -- read a file name, file need not exist. | |
846 | n -- read a number. | |
847 | c -- read a character and return it as a number. | |
848 | p -- use the numeric value of the prefix argument. | |
849 | P -- use raw value of prefix - can be nil, -, (NUMBER) or NUMBER. | |
850 | x -- read a Lisp object from the minibuffer. | |
851 | X -- read a Lisp form from the minibuffer and use its value. | |
852 | A null string means call interactively with no arguments. | |
853 | `doc' is documentation for the user. | |
