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 gtkTextBufferGetSlice and
gtkTextBufferGetText. Consider
gtkTextBufferCreateChildAnchor as a more convenient
alternative to this function. The buffer will add a reference to
the anchor, so you can unref it after insertion.gtkTextBufferInsertChildAnchor(object, iter, anchor)objectiteranchor
