gboolean            gwy_layer_func_register             (GType type);

Registeres a layer function (layer type).

type :

Layer type in GObject type system. That is the return value of gwy_layer_foo_get_type().

Returns :

Normally TRUE; FALSE on failure.

gwy_layer_func_foreach ()

void                gwy_layer_func_foreach              (GFunc function,
                                                         gpointer user_data);

Calls a function for each layer function.

function :

Function to run for each layer function. It will get function name (constant string owned by module system) as its first argument, user_data as the second argument.

user_data :

Data to pass to function.
