GtkTextBufferinsert_child_anchor

Inserts a child widget anchor into the text buffer at iter.

The anchor will be counted as one character in character counts, and when obtaining the buffer contents as a string, will be represented by the Unicode “object replacement character” 0xFFFC. Note that the “slice” variants for obtaining portions of the buffer as a string include this character for child anchors, but the “text” variants do not. E.g. see gtk_text_buffer_get_slice() and gtk_text_buffer_get_text().

Consider gtk_text_buffer_create_child_anchor() as a more convenient alternative to this function. The buffer will add a reference to the anchor, so you can unref it after insertion.
