void gtk_text_buffer_get_end_iter ( GtkTextBuffer* buffer, GtkTextIter* iter )
iter with the “end iterator,” one past the last valid
character in the text buffer. If dereferenced with
gtk_text_iter_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
gtk_text_buffer_get_start_iter() to get
character position 0) to the end iterator.
Iterator to initialize.
The argument will be set by the function. The data is owned by the caller of the function.
