Function: bs-buffer-list

bs-buffer-list is a byte-compiled function defined in bs.el.gz.

Signature

(bs-buffer-list &optional LIST SORT-DESCRIPTION)

Documentation

Return a list of buffers to be shown.

LIST is a list of buffers to test for appearance in Buffer Selection Menu. The result list depends on the global variables bs-dont-show-regexp, bs-must-show-regexp, bs-dont-show-function, bs-must-show-function and bs-buffer-sort-function. If SORT-DESCRIPTION isn't nil the list will be sorted by a special function. SORT-DESCRIPTION is an element of bs-sort-functions.
