1487 /* DEFUN - Define a built-in Lisp-visible C function or `subr'.
1488 `lname' should be the name to give the function in Lisp,
1489 as a null-terminated C string.
1490 `Fname' should be the C equivalent of `lname', using only characters
1491 valid in a C identifier, with an "F" prepended.
1492 The name of the C constant structure that records information
1493 on this function for internal use is "S" concatenated with Fname.
1494 `min_args' should be a number, the minimum number of arguments allowed.
1495 `max_args' should be a number, the maximum number of arguments allowed,
1496 or else MANY or UNEVALLED.
1497 MANY means pass a vector of evaluated arguments,
1498 in the form of an integer number-of-arguments
1499 followed by the address of a vector of Lisp_Objects
1500 which contains the argument values.
1501 UNEVALLED means pass the list of unevaluated arguments.
1502 `prompt' says how to read arguments for an interactive call.
1503 See the doc string for `interactive'.
1504 A null string means call interactively with no arguments.
1505 `arglist' are the comma-separated arguments (always Lisp_Objects) for
1507 The docstring for the function is placed as a "C" comment between
1508 the prompt and the `args' argument. make-docfile reads the
1509 comment and creates the DOC file from it.
