tail: A pointer to the last element of the queue.
length: The number of elements in the queue.

Functions

Instance methods

g_queue_clear

Removes all the elements in queue. If queue elements contain dynamically-allocated memory, they should be freed first.

since: 2.14

g_queue_clear_full

Convenience method, which frees all the memory used by a GQueue, and calls the provided free_func on each item in the GQueue.

since: 2.60

g_queue_copy

Copies a queue. Note that is a shallow copy. If the elements in the queue consist of pointers to data, the pointers are copied, but the actual data is not.

since: 2.4

g_queue_delete_link

Removes link_ from queue and frees it.

since: 2.4

g_queue_find

Finds the first link in queue which contains data.

since: 2.4

Finds an element in a GQueue, using a supplied function to find the desired element. It iterates over the queue, calling the given function which should return 0 when the desired element is found. The function takes two gconstpointer arguments, the GQueue element’s data as the first argument and the given user data as the second argument.

since: 2.4

g_queue_foreach

Calls func for each element in the queue passing user_data to the function.

since: 2.4

g_queue_free

Frees the memory allocated for the GQueue. Only call this function if queue was created with g_queue_new(). If queue elements contain dynamically-allocated memory, they should be freed first.

g_queue_free_full

Convenience method, which frees all the memory used by a GQueue, and calls the specified destroy function on every element’s data.

since: 2.32

g_queue_get_length

Returns the number of items in queue.

since: 2.4

g_queue_index

Returns the position of the first element in queue which contains data.

since: 2.4

g_queue_init

A statically-allocated GQueue must be initialized with this function before it can be used. Alternatively you can initialize it with G_QUEUE_INIT. It is not necessary to initialize queues created with g_queue_new().

since: 2.14
