Memory Allocators allocates chunks of memory for #GList, #GSList and #GNode. The #GAllocator is used as an efficient way to allocate small pieces of memory for use with the #GList, #GSList and #GNode data structures. It uses a #GMemChunk so elements are allocated in groups, rather than individually. The #GList, #GSList and #GNode implementations create default #GAllocator objects, which are probably sufficient for most purposes. These default allocators use blocks of 128 elements. To use your own #GAllocator, create it with g_allocator_new(). Then use g_list_push_allocator(), g_slist_push_allocator() or g_node_push_allocator() before any code which allocates new #GList, #GSList or #GNode elements respectively. After allocating the new elements, you must use g_list_pop_allocator(), g_slist_pop_allocator() or g_node_pop_allocator() to restore the previous allocators. Note that you cannot use the same allocator for #GList, #GSList and #GNode elements. Each must use separate allocators. The GAllocator struct contains private data. and should only be accessed using the following functions. Creates a new #GAllocator. @name: the name of the #GAllocator. This name is used to set the name of the #GMemChunk used by the #GAllocator, and is only used for debugging. @n_preallocs: the number of elements in each block of memory allocated. Larger blocks mean less calls to g_malloc(), but some memory may be wasted. (GLib uses 128 elements per block by default.) The value must be between 1 and 65535. @Returns: a new #GAllocator. Frees all of the memory allocated by the #GAllocator. @allocator: a #GAllocator.
