- * SECTION:priority_queues
- * @short_description: a collection of data entries with associated priority
- * values that returns entries one by one in order of priority
- *
- * <para>
- * The #GPQueue structure and its associated functions provide a sorted
- * collection of objects. Entries can be inserted in any order and at any time,
- * and an entry's priority can be changed after it has been inserted into the
- * queue. Entries are supposed to be removed one at a time in order of priority
- * with g_pqueue_pop(), but deleting entries out of order is possible.
- * </para>
- * <para>
- * The entries <emphasis>cannot</emphasis> be iterated over in any way other
- * than removing them one by one in order of priority, but when doing that,
- * this structure is far more efficient than sorted lists or balanced trees,
- * which on the other hand do not suffer from this restriction.
- * </para>
- * <para>
- * You will want to be very careful with calls that use #GPQueueHandle.
- * Handles immediately become invalid when an entry is removed from a #GPQueue,
- * but the current implementation cannot detect this and will do unfortunate
- * things to undefined memory locations if you try to use an invalid handle.
- * </para>
- * <note>
- * <para>
- * Internally, #GPQueue currently uses a Fibonacci heap to store
- * the entries. This implementation detail may change.
