gtk:text-buffer-modified (buffer)

buffer -- a gtk:text-buffer object
setting -- a boolean for the modification flag setting

Returns true if the text buffer has been modified. Used to keep track of whether the text buffer has been modified since the last time it was saved. Whenever the text buffer is saved to disk, call this function with the false value. When the text buffer is modified, it will automatically toggle on the modified bit again. When the modified bit flips, the text buffer emits a "modified-changed" signal.
