Variable: c-hanging-semi&comma-criteria

c-hanging-semi&comma-criteria is a customizable and buffer-local variable defined in cc-vars.el.gz.

Documentation

List of functions that decide whether to insert a newline or not.

The functions in this list are called, in order, whenever the auto-newline minor mode is activated (as evidenced by a /a or /ah string in the mode line), and a semicolon or comma is typed (see c-electric-semi&comma). Each function in this list is called with no arguments, and should return one of the following values:

  nil -- no determination made, continue checking
  stop -- do not insert a newline, and stop checking
  (anything else) -- insert a newline, and stop checking

If every function in the list is called with no determination made, then no newline is inserted.

This is a style variable. Apart from the valid values described above, it can be set to the symbol set-from-style. In that case, it takes its value from the style system (see c-default-style and c-style-alist) when a CC Mode buffer is initialized. Otherwise, the value set here overrides the style system (there is a variable c-old-style-variable-behavior that changes this, though).
