/*         Definitions of primitive Lisp functions and variables        */
/************************************************************************/


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