/* 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.
 `min_args' should be a number, the minimum number of arguments allowed.
 `max_args' 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.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
