                                             gpointer user_data);
GList*      gst_filter_run                  (const GList *list,
                                             GstFilterFunc func,
                                             gboolean first,

gst_filter_run ()

GList*      gst_filter_run                  (const GList *list,
                                             GstFilterFunc func,
                                             gboolean first,

Iterates over the elements in list, calling func with the list item data for each item. If func returns TRUE, data is prepended to the list of results returned. If first is true, the search is halted after the first result is found.

list : a linked list
func : the function to execute for each item
first : flag to stop execution after a successful item
user_data : user data
Returns : the list of results
