1505 `lname' should be the name to give the function in Lisp,
1506 as a null-terminated C string.
1507 `Fname' should be the C equivalent of `lname', using only characters
1508 valid in a C identifier, with an "F" prepended.
1509 The name of the C constant structure that records information
1510 on this function for internal use is "S" concatenated with Fname.
1511 `min_args' should be a number, the minimum number of arguments allowed.
1512 `max_args' should be a number, the maximum number of arguments allowed,
1513 or else MANY or UNEVALLED.
1514 MANY means pass a vector of evaluated arguments,
1515 in the form of an integer number-of-arguments
1516 followed by the address of a vector of Lisp_Objects
1517 which contains the argument values.
1518 UNEVALLED means pass the list of unevaluated arguments.
1519 `prompt' says how to read arguments for an interactive call.
1520 See the doc string for `interactive'.
1521 A null string means call interactively with no arguments.
1522 `arglist' are the comma-separated arguments (always Lisp_Objects) for
1524 The docstring for the function is placed as a "C" comment between
1525 the prompt and the `args' argument. make-docfile reads the
