gtk-text-iter-find-char (iter predicate &key limit direction)

iter -- a gtk-text-iter instance
pred -- a gtk-text-char-predicate callback function to be called on each character
limit -- a gtk-text-iter instance with a search limit, or nil for none
direction -- the value :forward indicates forward search and the value :backward backward search

A boolean whether a match was found.

This is a convenience function of the Lisp implementation which combines the functions gtk-text-iter-forward-find-char and gtk-text-iter-backward-find-char into one single function.

The direction of the search is indicated with the keyword argument direction which has a default value of :forward for forward search. For backward search the argument direction takes the value :backward.

In addition the argument limit is a keyword argument with the default value nil.
