866 `lname' should be the name to give the function in Lisp,
867 as a null-terminated C string.
868 `fnname' should be the name of the function in C.
869 By convention, it starts with F.
870 `sname' should be the name for the C constant structure
871 that records information on this function for internal use.
872 By convention, it should be the same as `fnname' but with S instead of F.
873 It's too bad that C macros can't compute this from `fnname'.
874 `minargs' should be a number, the minimum number of arguments allowed.
875 `maxargs' should be a number, the maximum number of arguments allowed,
876 or else MANY or UNEVALLED.
877 MANY means pass a vector of evaluated arguments,
878 in the form of an integer number-of-arguments
879 followed by the address of a vector of Lisp_Objects
880 which contains the argument values.
881 UNEVALLED means pass the list of unevaluated arguments
882 `prompt' says how to read arguments for an interactive call.
883 This can be zero or a C string.
884 Zero means that interactive calls are not allowed.
885 A string is interpreted in a hairy way:
886 it should contain one line for each argument to be read, terminated by \n.
887 The first character of the line controls the type of parsing:
890 k -- read a key sequence and return it as a string.
891 a -- read a function name (symbol) with completion.
892 C -- read a command name (symbol) with completion.
893 v -- read a variable name (symbol) with completion.
894 b -- read a buffer name (a string) with completion.
895 B -- buffer name, may be existing buffer or may not be.
896 f -- read a file name, file must exist.
897 F -- read a file name, file need not exist.
899 c -- read a character and return it as a number.
900 p -- use the numeric value of the prefix argument.
901 P -- use raw value of prefix - can be nil, -, (NUMBER) or NUMBER.
902 x -- read a Lisp object from the minibuffer.
903 X -- read a Lisp form from the minibuffer and use its value.
904 A null string means call interactively with no arguments.
905 `doc' is documentation for the user.
