1445 /* DEFUN - Define a built-in Lisp-visible C function or `subr'.
1446 `lname' should be the name to give the function in Lisp,
1447 as a null-terminated C string.
1448 `Fname' should be the C equivalent of `lname', using only characters
1449 valid in a C identifier, with an "F" prepended.
1450 The name of the C constant structure that records information
1451 on this function for internal use is "S" concatenated with Fname.
1452 `min_args' should be a number, the minimum number of arguments allowed.
1453 `max_args' should be a number, the maximum number of arguments allowed,
1454 or else MANY or UNEVALLED.
1455 MANY means pass a vector of evaluated arguments,
1456 in the form of an integer number-of-arguments
1457 followed by the address of a vector of Lisp_Objects
1458 which contains the argument values.
1459 UNEVALLED means pass the list of unevaluated arguments.
1460 `prompt' says how to read arguments for an interactive call.
1461 See the doc string for `interactive'.
1462 A null string means call interactively with no arguments.
1463 `arglist' are the comma-separated arguments (always Lisp_Objects) for
1465 The docstring for the function is placed as a "C" comment between
1466 the prompt and the `args' argument. make-docfile reads the
1467 comment and creates the DOC file from it.
