int gtk_text_iter_compare ( const GtkTextIter* lhs, const GtkTextIter* rhs )
A qsort()-style function that returns negative if
lhs is less than
rhs, positive if
lhs is greater than
rhs, and 0 if they’re equal.
Ordering is in character offset order, i.e. the first character in the buffer is less than the second character in the buffer.
The data is owned by the caller of the function.
