Function: run-hook-with-args-until-failure

run-hook-with-args-until-failure is a function defined in eval.c.

Signature

(run-hook-with-args-until-failure HOOK &rest ARGS)

Documentation

Run HOOK with the specified arguments ARGS.

HOOK should be a symbol, a hook variable. The value of HOOK may be nil, a function, or a list of functions. Call each function in order with arguments ARGS, stopping at the first one that returns nil, and return nil. Otherwise (if all functions return non-nil, or if there are no functions to call), return non-nil
(do not rely on the precise return value in this case).

Do not use make-local-variable to make a hook variable buffer-local. Instead, use add-hook and specify t for the LOCAL argument.
