next-error-function is a variable defined in `simple.el'.
Its value is

nil

• Automatically becomes buffer-local when set.
• This variable may be risky if used as a file-local variable.

Documentation:
Function to use to find the next error in the current buffer.
The function is called with 2 parameters:
ARG is an integer specifying by how many errors to move.
RESET is a boolean which, if non-nil, says to go back to the beginning
of the errors before moving.
Major modes providing compile-like functionality should set this variable
to indicate to `next-error' that this is a candidate buffer and how
to navigate in it.
