next-error-find-buffer
next-error-find-buffer is a compiled Lisp function in `simple.el
'.
(next-error-find-buffer &optional AVOID-CURRENT EXTRA-TEST-INCLUSIVE EXTRA-TEST-EXCLUSIVE)
Return a `next-error' capable buffer.
If AVOID-CURRENT is non-nil, treat the current buffer
as an absolute last resort only.
The function EXTRA-TEST-INCLUSIVE, if non-nil, is called in each buffer
that normally would not qualify. If it returns t, the buffer
in question is treated as usable.
The function EXTRA-TEST-EXCLUSIVE, if non-nil, is called in each buffer
that would normally be considered usable. If it returns nil,
that buffer is rejected.
