#ifndef LISP_COMMAND_LOOP
/* The guts of the command loop are in command_loop_1(). This function
doesn't catch errors, though -- that's the job of command_loop_2(),
which is a condition-case wrapper around command_loop_1().
command_loop_1() never returns, but may get thrown out of.
When an error occurs, cmd_error() is called, which usually
invokes the Lisp error handler in `command-error'; however,
a default error handler is provided if `command-error' is nil
(e.g. during startup). The purpose of the error handler is
simply to display the error message and do associated cleanup;
it does not need to throw anywhere. When the error handler
finishes, the condition-case in command_loop_2() will finish and
command_loop_2() will reinvoke command_loop_1().
command_loop_2() is invoked from three places: from
initial_command_loop() (called from main() at the end of
internal initialization), from the Lisp function `recursive-edit',
and from call_command_loop().
call_command_loop() is called when a macro is started and when the
minibuffer is entered; normal termination of the macro or
minibuffer causes a throw out of the recursive command loop. (To
'execute-kbd-macro for macros and 'exit for minibuffers. Note also
that the low-level minibuffer-entering function,
`read-minibuffer-internal', provides its own error handling and
does not need command_loop_2()'s error encapsulation; so it tells
call_command_loop() to invoke command_loop_1() directly.)
Note that both read-minibuffer-internal and recursive-edit set
up a catch for 'exit; this is why `abort-recursive-edit', which
throws to this catch, exits out of either one.
initial_command_loop(), called from main(), sets up a catch
for 'top-level when invoking command_loop_2(), allowing functions
to throw all the way to the top level if they really need to.
Before invoking command_loop_2(), initial_command_loop() calls
top_level_1(), which handles all of the startup stuff (creating
the initial frame, handling the command-line options, loading
the user's .emacs file, etc.). The function that actually does this
is in Lisp and is pointed to by the variable `top-level';
normally this function is `normal-top-level'. top_level_1() is
just an error-handling wrapper similar to command_loop_2().
Note also that initial_command_loop() sets up a catch for 'top-level
when invoking top_level_1(), just like when it invokes
command_loop_2(). */
