get_end_iter
Description:
Initializes iter with the “end iterator,” one past the last valid character in the text buffer.
If dereferenced with [method@Gtk.TextIter.get_char], the end iterator has a character value of 0. The entire buffer lies in the range from the first position in the buffer (call [method@Gtk.TextBuffer.get_start_iter] to get character position 0) to the end iterator.
Parameters:
| this |
a `GtkTextBuffer` |
| iter |
iterator to initialize |
