1508 `lname' should be the name to give the function in Lisp,
1509 as a null-terminated C string.
1510 `Fname' should be the C equivalent of `lname', using only characters
1511 valid in a C identifier, with an "F" prepended.
1512 The name of the C constant structure that records information
1513 on this function for internal use is "S" concatenated with Fname.
1514 `min_args' should be a number, the minimum number of arguments allowed.
1515 `max_args' should be a number, the maximum number of arguments allowed,
1516 or else MANY or UNEVALLED.
1517 MANY means pass a vector of evaluated arguments,
1518 in the form of an integer number-of-arguments
1519 followed by the address of a vector of Lisp_Objects
1520 which contains the argument values.
1521 UNEVALLED means pass the list of unevaluated arguments.
1522 `prompt' says how to read arguments for an interactive call.
1523 See the doc string for `interactive'.
1524 A null string means call interactively with no arguments.
1525 `arglist' are the comma-separated arguments (always Lisp_Objects) for
1527 The docstring for the function is placed as a "C" comment between
1528 the prompt and the `args' argument. make-docfile reads the
1529 comment and creates the DOC file from it.
