copy_shared_pointer()

template<typename T>

void blender::implicit_sharing::copy_shared_pointer	(	T *	src_ptr,
		const ImplicitSharingInfo *	src_sharing_info,
		T **	r_dst_ptr,
		const ImplicitSharingInfo **	r_dst_sharing_info )

Copy shared data from the source to the destination, adding a user count.

Note

Does not free any existing data in the destination.

free_shared_data()

template<typename T>

void blender::implicit_sharing::free_shared_data	(	T **	data,
		const ImplicitSharingInfo **	sharing_info )

Remove this reference to the shared data and remove dangling pointers.

info_for_mem_free()

const ImplicitSharingInfo * blender::implicit_sharing::info_for_mem_free

(

void *

data

)

Create an implicit sharing object that takes ownership of the data, allowing it to be shared. When it is no longer used, the data is freed with MEM_freeN, so it must be a trivial type.

make_trivial_data_mutable()

template<typename T>

void blender::implicit_sharing::make_trivial_data_mutable	(	T **	data,
		const ImplicitSharingInfo **	sharing_info,
		const int64_t	size )

Make data mutable (single-user) if it is shared. For trivially-copyable data only.

void blender::implicit_sharing::resize_trivial_array	(	T **	data,

Resize an array of shared data. For trivially-copyable data only. Any new values are not initialized.
