c-electric-backspacec-electric-backspace is an interactive compiled Lisp function in `
cc-cmds.el'. (c-electric-backspace ARG) Delete the preceding character or whitespace. If `c-hungry-delete-key' is non-nil (indicated by "/h" on the mode line) then all preceding whitespace is consumed. If however a prefix argument is supplied, or `c-hungry-delete-key' is nil, or point is inside a literal then the function in the variable `c-backspace-function' is called.
