c-toggle-hungry-statec-toggle-hungry-state is an interactive compiled Lisp function in `
cc-cmds.el'. (c-toggle-hungry-state &optional ARG) Toggle hungry-delete-key feature. Optional numeric ARG, if supplied, turns on hungry-delete when positive, turns it off when negative, and just toggles it when zero or left out. When the hungry-delete-key feature is enabled (indicated by "/h" on the mode line after the mode name) the delete key gobbles all preceding whitespace in one fell swoop.
